->''"In many of the more relaxed civilizations on the Outer Eastern Rim of the Galaxy, the Hitch-Hiker's Guide has already supplanted the great Encyclopaedia Galactica as the standard repository of all knowledge and wisdom, for though it has many omissions and contains much that is apocryphal, or at least wildly inaccurate, it scores over the older, more pedestrian work in two important respects. First, it is slightly cheaper; and secondly it has the words DON'T PANIC inscribed in large friendly letters on its cover."''

Quotes from other [[FictionalDocument fictional books]] being used as an {{Epigraph}} or part of the [[FramingDevice frame]] of the story. They are not part of the text proper.

These quotes are always apposite, and often provide painless {{exposition}}, rather than relying on AsYouKnow - style conversations. In SpeculativeFiction, fictitious encylopedias are often used, such as Asimov's ''Encyclopedia Galactica''. Journal entries or biographies can also be used. Can be part of a ScrapBookStory. In VideoGames these tend to be more-or-less random and [[FlavorText not immediately relevant to the story]] and can be used give the player something to read on a LoadingScreen.

[[folder: Fan Fiction ]]
* In the essay-fic, [[FanFic/EquestriaAHistoryRevealed Equestria: A History Revealed]], the LemonyNarrator cites an encyclopedia as a reference a few times. In the bibliography however, that encyclopedia is revealed to be the school filly, [[ShoutOut Sweetie]] [[MemeticMutation Belle]].
* At the start of each chapter of ''Fanfic/KyonBigDamnHero'' there are extracts of self-help books on being a hero, some poetry, or texts that are implied to be from future documents/books, usually relevant to the chapter.
* ''FanFic/TiberiumWars'' likes to begin each chapter with a quote from one of the characters involved, and often ends with a hefty excerpt from military intelligence reports or research papers, [[ShownTheirWork making it clear that the author's done his work]] and knows his way around the Tiberium 'verse.
* By the same author, ''FanFic/{{Renegade}}'' features Codex entries in line with those from ''Franchise/MassEffect'', to better explain how [[FusionFic the addition]] of [[VideoGame/CommandAndConquerTiberianSeries Tiberium]] to the setting has made things very different.
** ''Fanfic/MassEffectHumanRevolution'' does the same, leaving a note(s) at the end of chapters for anything new that shows up in lieu of an InfoDump in story written like an entry in the codex (or in one instance, a report to the Shadow Broker.).
** Codex entries seem to be the rule rather than exception in ''Mass Effect'' fan fiction with any non-canon WorldBuilding. Especially in crossovers.
** ''Fanfic/XCOMSecondContact'', instead has articles in the style of ''VideoGame/XCom'' [=UFOpeadia=]. Like Turian autopsy report with plans to weaponize their skin as radiation shielding.
* In the ''WesternAnimation/InvaderZim'' fanfic, [[http://www.fanfiction.net/s/4018157/1/In-Short-Supply InShortSupply]], each chapter begins with an excerpt from a "factual" document, usually about the Irken species, providing vital information on things from their reproduction to time scales.
* ''Fanfic/ToTheStars'' is set centuries ahead of the [[Anime/PuellaMagiMadokaMagica magical girl anime]] on which it's based, where their existence has become known. Naturally they were militarized by the government; the chapters not only begin with relevant background information by magical girl historians, but also excerpts from MG military manuals.
* In the ''WesternAnimation/DannyPhantom[=/=]Film/{{Beetlejuice}}'' {{Crossover}} ''FanFic/SayItThrice'', a lot of the WorldBuilding and such are delivered in this manner. At the start of chapters are excerpts from sources such as ''[[Film/{{Beetlejuice}} The Handbook for the Recently Deceased, The Living and the Dead,]]'' and even [[WesternAnimation/DannyPhantom the scientific journals of Maddie Fenton]].
* FanFic/TheLoneTraveler, starting partway through the second story, has each chapter start with an excerpt from ''Legends & Myths of the Wizarding World'' by Gertrude Yolanda as an OpeningNarration. The very end of the third story introduces a newly created excerpt from [[Series/BuffyTheVampireSlayer Rupert Giles' Watcher's Diaries]] that becomes the new OpeningNarration.

* In the film ''Film/TwoThousandTwelve'', Jackson Curtis's unsuccessful sci-fi novel ''Farewell Atlantis'' is symbolically important and is brought up throughout the film. Parts of it are read aloud on two or three occasions.
* In ''Film/{{Coherence}}'', the book Hugh's brother left provides the characters with {{Info Dump}}s about quantum decoherence which helps to understand the strange phenomena going on.

* The ''Encyclopedia Galactica'', Creator/IsaacAsimov's ''Literature/{{Foundation}}'' series.
* ''The Book of Counted Sorrows'', Creator/DeanKoontz, repeatedly.
* ''The Book of Counted Joys'', Creator/DeanKoontz, not quite as often.
* The Secret Book of Cadwallon the Druid, ''Literature/{{Deverry}}''.
* Princess Irulan's histories in ''Literature/{{Dune}}''. All of Frank Herbert's ''Dune'' novels make use of this, quoting from fictional (auto)biographies, treatises on religion/politics, journals...
** Almost every other major work by Herbert.
* Orson Scott Card does this in ''Literature/EndersGame'' and ''Literature/SpeakerForTheDead''.
* A few sources of the {{epigraph}}s in Creator/KatherineKurtz's works are from within the ''Literature/{{Deryni}}'' universe. The first chapter of ''Deryni Checkmate'' has an epigraph from a "St. Veneric" which mentions the fickleness of Gwynedd's weather in March, and chapter fifteen of the same book has this from an unknown Deryni monk: "The humans kill what they do not understand."
* The Guide itself, ''Franchise/TheHitchhikersGuideToTheGalaxy.''
** And sometimes the ''Encyclopaedia Galactica'' in the series, although the Guide has the major selling point of being slightly cheaper and having "'''Don't Panic'''" printed in large friendly letters on the cover (as well as not taking up a parking lot).
** Also subverted; sometimes the Guide's entries are full of non-sequiturs and gags completely irrelevant to the story. Sometimes these are never mentioned again, and sometimes they become plot-critical {{brick joke}}s as a double-subversion.
* The biography of Literature/ThursdayNext, and several other fictional documents, in the ''Thursday Next'' series.
* Every chapter in the ''Literature/NurseryCrime'' series begins this way. The first book uses quotes from various local newspapers, while the second book draws exclusively from ''The Bumper Book of Berkshire Records''.
* The introduction to Michael Crichton's ''Literature/TheAndromedaStrain'' is written as an introduction to some official report of the events of the novel. All his novels after that one followed suit.
* Juliet [=McKenna=] likes them even more; she prefaces nearly every chapter with a fictional document, some of them only tangentially relevant.
* ''The Encyclopedia of Marvels, Life Forms and Other Phenomena of Zamonia and its Environs'' in ''Literature/TheThirteenAndAHalfLivesOfCaptainBluebear''.
%%* The protagonist's "Rules and Things to Having a Funner Life" in ''Bud Not Buddy''.
* The title and chapter pages of Creator/StephenKing's more epic novels quote anything and everything from T.S. Eliot and Thomas Wolfe to Blue Oyster Cult and King's own fictional characters.
* The ''[[Literature/RealmOfTheElderlings Farseer]]'' and ''Tawny Man'' trilogies by Creator/RobinHobb.
* The ''Literature/MythAdventures'' humorous fantasy novels written by Robert Lynn Asprin. Each chapter has a fictitious quote. An example might be something like, "Violence is never the right thing to do" - Attila the Hun.
** Asprin has commented that he bitterly came to regret doing this, as making up all the quotes proved to be the hardest part of writing the novels. The later books in the series drop the practice.
* Jack [=McKinney's=] ''Anime/{{Robotech}}'' [[TieInNovel Tie-In Novels]] use quotes from various in-universe sources to comment on the events of each chapter.
* ''Literature/TheToughGuideToFantasyland'' by Creator/DianaWynneJones calls these "gnomic utterances". One of her novels, ''Literature/FireAndHemlock'', also uses quotes from the ballads "Literature/TamLin" and "Thomas the Rhymer" in this way.
* The prologue of ''[[Literature/YoungWizards So You Want To Be A Wizard]]'' quotes extensively from the [[GreatBigBookOfEverything wizard's manual]] in order establish what wizards are and how [[InsistentTerminology wizardry]] works.
** The ''Literature/YoungWizards'' series in general contains a few quotes from the ''Book of Night with Moon''.
* ''Literature/AmericanGods'' has quotations from a book being written by one of the characters, Mr Ibis.
* ''Literature/JonathanStrangeAndMrNorrell'' did this frequently; the characters often debated the relative merits of the books.
* Pournelle's ''Literature/CoDominium'' series:
** In ''Literature/FalkenbergsLegion'', it is used sparingly, with about 3-4 entries in the work. Latter novels ''Go Tell the Spartans'' and ''Prince of Sparta'' have excerpts from a number of sources, including essays, news reports, and even letters, in the beginning of each chapter.
** In ''Literature/TheMoteInGodsEye'', excerpts appear when characters decide to look them up on their [=PDAs=], and flow smoothly with the narration.
** Oddly enough, the sequel to ''The Mote in God's Eye'' actually (for the most part) uses real historical quotes.
** Pournelle's collaborator, Creator/LarryNiven, is also very fond of this. His book ''Destiny's Road'' is full of quotes from planetary science surveys, local lore regarding the colonization of an alien world and the ultimate fate of some colonists, and quotes regarding local customs. A very early chapter opens rather ominously quoting an excerpt of a military absentee court-martial.
* Every chapter in the ''Literature/SecondApocalypse'' series opens with one or two quotes from InUniverse works, many of which are philosophical or historical in nature. One notable such work is a history of the events of the first trilogy, written after the fact by Drusas Achamian, one of the main characters, which makes the first trilogy also a mild case of DirectLineToTheAuthor.
* ''Literature/TheWheelOfTime'': In-universe books are often quoted before the prologue or after the epilogue of a book. Typically, the quotations are from history books written after the end of the series, or prophecies written long before.
* ''Literature/{{Animorphs}}'' does this in a couple of books.
* ''Literature/{{Redwall}}''
* ''Literature/HouseOfLeaves''. Either half of it, or all of it, or if you're really brave, none of it.
* Creator/RobertRankin has ''The Suburban Book of the Dead'', the rewritten ''Suburban Book of the Dead'', works by the guru's guru Hugo Rune, and works ''about'' Hugo Rune by Sir John Rimmer. And that's just for starters.
* Creator/TerryPratchett's ''Literature/NomesTrilogy'' features epigraphs from ''The Book of Nome'' (a CargoCult religious text) in the first two books and ''A Scientific Encyclopedia For The Enquiring Young Nome'' (which misunderstands things almost as much, but in a different way) in the third.
** ''Discworld/AHatFullOfSky'' starts with an excerpt from ''Fairies and How to Avoid Them''. It also contains part of a text on capturing hivers, although that stops when the writer goes crazy and, it's implied, gets more or less vaporized.
* Cantra yos'Phelium's logbook in the ''[[Literature/LiadenUniverse Liaden]]'' series.
* Each of Creator/DavidEddings' books opens with a short piece of narrative taken from historical records, history books, or religious doctrines within the context of the story. These serve to establish the setting and bring the reader up to speed, sometimes serving as a roundabout recap or providing context for the events. For instance, ''Literature/DomesOfFire'', the first book of ''Literature/TheTamuli'' trilogy, starts with a record from the Tamuli government summarizing the events in the previous trilogy, ''Literature/TheElenium''; the fictive author shows a great deal of secularism by dismissing cases of divine or supernatural influence as superstitious exaggeration, and criticizes unfamiliar government practices such as voting or female rulers. The second, ''Literature/TheShiningOnes'', recaps more events but is explicitly written by a different author while part of the same record and calls into question the previous chapter's take on things.
* The ''Literature/DaughterOfTheLioness'' have quotes of useful bits of advice Aly got at the start of each chapter - stuff from books, people she knows, etc. One example is Daine telling her that the Gods can sense lies, but if you don't make them suspicious enough to read your mind, they won't know if you [[LieOfOmission left something out]].
* ''Literature/TheWarAgainstTheChtorr''. "A Season for Slaughter" heads each chapter with [[InfoDump extensive]] quotes from the "Red Book", a guide to the alien invaders to which the protagonist has contributed heavily.
* Baron Bodissey's ''Life'' in Creator/JackVance's ''Gaean Reach'' novels: it's a twelve-volume-long philosophical encyclopedia which Vance often quotes, at length, for use as chapter headings. The entries aren't always entirely relevant, but this being Vance, they're always delightful. In ''Literature/TheDemonPrinces'', there is also the criminal psychology manual ''The Demon Princes'' by Caril Carphen.
** Bodissey's omnipresence is later lampshaded; a character guesses that the latest IceCreamKoan is from Bodissey, since he's said practically everything.
** Also quoted in ''Literature/TheDemonPrinces'' are several reviewers who make very hostile comments about the Baron. One expresses the desire to give Baron Bodissey a severe thrashing -- and then buy him a drink.
* Pudd'nhead Wilson's Calendar from Creator/MarkTwain's ''Pudd'nhead Wilson.''
* The ''[[Literature/PrinceRoger Empire of Man]]'' series follows in Eddings' footsteps by having the book open with commentary from a biographer who is writing from a much later point after the events in the books. Some of the things the biographer says are quite important, especially the bits that show that [[spoiler: Roger never really shakes the reputation the BigBad planted that he killed his family and drove his mother mad in order to force her to abdicate so that he could take over the Empire]].
* ''Literature/CatsCradle'' has excerpts from the Books of Bokonon to explain Bokononist philosophy.
* Every chapter of books in the ''Franchise/StarWars: Republic Commando'' series is preceded by an excerpt from an in-universe document. One book even had a Mandalorian-to-English dictionary as an appendix.
* The novel-length ''Literature/CiaphasCain'' stories contain "excerpts" from various fictional sources--often Jenit Sulla's [[PurpleProse unreadable]] biography--in-between chapters.
* Creator/RobertEHoward puts epigraphs of dramatically manly poetry before each chapter of ''[[Franchise/ConanTheBarbarian The Phoenix On The Sword]]'', but does not do this for other Conan stories.
* Creator/CharlesSheffield's ''Summertide'' (book 1 of the Heritage Universe) has excerpts from Lang's Catalogue of Builder Artifacts to explain the mysterious structures mentioned throughout the book. Extra points to the fact that the author of the catalogue is a main character.
* Literature/TheGrimnoirChronicles uses quotes from a variety of sources at the beginning of each chapter. Some are from or about characters in the books, but many just fill in details of the world, such as UsefulNotes/TheodoreRoosevelt dying in combat against the Kaiser's zombies in UsefulNotes/WorldWarI.
* Played with in Creator/KeithLaumer's ''Literature/{{Retief}}'' series. Many of the stories start with an excerpt from the official records of the CDT, explaining the story you're about to read. The official version never comes ''close'' to describing what actually happened, and Retief is rarely mentioned, let alone given credit for saving the day.
* Some ''Franchise/DoctorWhoExpandedUniverse'' novels have these. ''Theatre of War'' has excerpts from its fictional playwright's work, and scholarly works about his plays and theatre in general. ''The Also People'' quotes fictional pop songs, including regular DWEU [[TheGhost unseen background character]] Johnny Chess, Silurian punk ("Outta My Way, [[SonOfAnApe Monkeyboy]]" by Third Eye), and Cyberman blues ("Tears of Rust" by Cyberblind).
* In Donald Kingsbury's ''Literature/CourtshipRite'', each chapter starts with a quote from a fictional historical or religious document of Geta. Many of them are charmingly disturbing.
* The ''Literature/PriscillaHutchins'' series uses journal entries, newspaper clippings, and the like to give you some perspective on the story, with two unusual features: one, the entries appear at the ''end'' of a chapter, to give you some perspective on what you just read, and two, you occasionally get a whole list of newspaper headlines, which not only gives you a broader perspective on the setting, but lets you see how far up list of top stories the story you're following has gotten.
* ''Literature/TheStoneDanceOfTheChameleon'' prefaces all its chapters with excerpts from in-universe documents, most often the writings of the Wise.
* ''Literature/HeroicsForBeginners'': Each chapter starts with a quote from ''The Handbook of Practical Heroics'' that happens to be relevant to the events of the chapter.
* Creator/BrandonSanderson uses this trope with his longer works. Specifically:
** In the [[Literature/MistbornTheOriginalTrilogy Mistborn Trilogy]] each book has epigraphs that are taken from an in-universe text that the characters discover at some point in the story.
** In Literature/TheStormlightArchive each section of each book follows a theme, from ancient texts to letters to quotations from the dying, all in-universe sources.
* Each section of ''[[Literature/ElementalLogic Fire Logic]]'' is prefaced by quotes from three imaginary books: Mackapee's ''Principles for Community'', Mabin's ''Warefare'', and Medric's ''History of My Father's People''. Mackapee was an ancient earth witch whose book became the basis of Shaftali culture and ideals. Mabin is a leader of LaResistance who is becoming very like the Sainnite invaders she so hates. And Medric, son a Sainnite man and a Shaftali woman, is trying to make peace between both peoples, because he realizes that the alternative is the destruction of both the Sainnites in Shaftal and much of Shaftali culture. Their views suggest the past, present, and future of the country, and the writing and distribution of Medric's book is a major plot in the sequel.
* Creator/{{Carl Sagan}}'s ''Cosmos'' presents three extracts from the ''Encyclopedia Galactica'' about three intelligent species of the Milky Way, detailing among other things data on its home star and planet, biochemistry, mean mass and lifetime, and survival probability within a determinate amount of time [[spoiler: We're the third species detailed there and things look bleak for our future existence]]
* Every chapter of ''Literature/TheDinosaurLords'' starts with an extract from either ''The Book Of True Names'', which speaks about species of dinosaurs and their applications in society, or ''A Primer To Paradise For The Improvement Of Young Minds'', which focuses on FantasyPantheon of Paradise.
* Several of the novels in the ''Literature/ArrivalsFromTheDark'' and ''Trevelyan's Mission'' series make use of fictional texts to provide exposition, which doesn't stop the protagonist from repeating some of those facts later. In particular, ''The Faraway Saikat'' has every chapter end with a passage from one of the four or five fictional books on the [[HumanAliens Kni'lina]] mentioned early on, describing the race's history, politics, culture, and religion (for example, ''Analogies between Buddhism and Yezdan'tabi'' by Pal Bonjipadhal).

* The booklets of Music/{{Dragonland}}'s album ''The Battle Of The Ivory Plains'', ''Holy War'', and ''Under The Grey Banner'' feature extracts from fictional books of the setting shared by the three albums.[[/folder]]


* Gene Rodenberry's ''Series/{{Andromeda}}'' prefaces its episodes with quotes from all manner of things, including famous philosophers, poets and commanders (some real, some fictional), battle-hymns of some of the setting's militaries, and on one memorable occasion an Argosy Special Operations requisition form.
->[[center:Requested: One Mark V ECM unit, 1000km of Fullerene cable, one low-yield nuclear warhead.]]\\
[[center:Purpose: [[BlatantLies Surprise party for a foreign dignitary]]. ]]
* Speaking of Gene Rodenberry works, the CaptainsLog trope that ''Franchise/StarTrek'' named and codified often functions as a spoken-aloud variant of this one.
* Episodes of ''Series/{{Grimm}}'' generally begin with a quote from the fairy story or legend on which the episode is (sometimes very loosely) based.

[[folder: Tabletop Games ]]

* ''Sarpadian Empires'', which provides much of the flavor text to the "Fallen Empires" expansion of ''TabletopGame/MagicTheGathering''. Much of ''Magic's'' flavor text counts as this, actually, but this is the most iconic example. ''[[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=114921 Sarpadian Empires, Vol. VII]]'' appears as an actual card in the ''Time Spiral'' set.
** Many Kamigawa block cards quoted extensively from fictional sources, as flavorwise the texts represent a retrospective historical view of the Kami War. The most common source to be quoted from is ''The History of Kamigawa'', including a [[http://ww2.wizards.com/gatherer/CardDetails.aspx?&id=74604 card]] of the original [[strike:author]] tome.
* Too many to count in the margins of ''TabletopGame/{{Nobilis}}'', most notably the works of Emily Chen (''Doorknobs'', ''Viridian'', ''A Small Detour To Altair'' and others), Kneader Guy (''Earth Stories'', ''Air Stories'', ''Fire Stories'', ''Water Stories'' and ''Void Stories''), Luc Ginnes (''On Serving the Nobilis'', ''Legends of the Nobilis'' and ''Void Stories''), Jackie Robinson (''Parables for Our Modern Age'' and ''Small Gods''), Merriweather James (''Principals of The Dark''), and Agusta Valentina (''A Philosophy of Treason''). So extensive was the collection of works with "excerpts" in the book that many readers were surprised to learn that none of them were real.
** Third edition introduces ''The Voice of Morrowen Hollow'', a book created specifically for the character creation section of Antithesis 1i, which deals with...well...[[BrownNote the Voice]] [[EldritchAbomination of Morrowen Hollow]].
* A variation appears in many ''TabletopGame/{{Shadowrun}}'' sourcebooks, where a running discussion of the main text, in electronic discussion forum format and complete with the occasional off-topic digression, will appear in the margins or along the bottoms of a book's pages.
* White Wolf ''loves'' these, especially in [[TabletopGame/OldWorldOfDarkness both]] [[TabletopGame/NewWorldOfDarkness versions]] of ''The World Of Darkness''.
* ''TabletopGame/{{Paranoia}}: XP Service Pack 1'' has numerous examples. Early in the book, one of the pages is duplicated with text messages from hackers covering it, and the first letter of every sentence supposedly spelling out a secret message: "MIKE-U LIVES".
** The next page repeats the trick: "NO HE DOESN'T".
** The 2nd edition rulebook presents "Tips for Traitors" as an excerpt from a much larger in-universe document.
*** Reading the above is considered metagaming. Metagaming is treason. [[RunningGag Please report immediately to your nearest Termination Booth.]]
* The ''Van Richten's Guide'' series of ''TabletopGame/{{Ravenloft}}'' supplements use this device constantly, both as in-character 'citations' by in-character "author" Van Richten, and as flavor-text sidebars. Such references come from personal journals, ship's logs, letters, and other written testimony from individuals who have encountered dangerous monsters; hence, the UndeadAuthor trope often comes into play. Sometimes literally.
* ''TabletopGame/{{Warhammer 40000}}'''s Codices and rulebooks are littered with character quotes or extracts from top-secret Inquisitorial reports, to provide an extra bit of background and flavor while giving certain elements of the fanbase [[ContinuitySnarl something to argue about]].


* In the musical ''Theatre/HowToSucceedInBusinessWithoutReallyTrying'', the protagonist repeatedly turns to an advice book of the same name.
** Which ''actually exists'': Shepherd Mead wrote a series of cartoon books in the 1950s which were parodies of then-current how-to books, one of which provided the title and inspiration for the musical. [[http://www.amazon.com/Succeed-Business-Without-Really-Trying/dp/0684800209/ref=ntt_at_ep_dpi_1 The book]] was republished in 1995 with the revival of the musical.


[[folder: Video Games ]]
* The Codex in the ''Franchise/MassEffect'' series is an in-universe document and therefore limited to what is public knowledge, not what the player [[TheReveal finds out]]. It is also occasionally made [[GasLeakCoverup deliberately wrong]] by its in universe makers; one shining example is in ''[[VideoGame/MassEffect2 ME2]]'' when you look up 'Sovereign'--apparently, Mr. Vanguard-of-Our-Destruction was a geth ship that just happened to look like a Reaper. In the ExpandedUniverse novel ''Literature/MassEffectAscension'', the character [[TheRainman Gillian Grayson]] starts reciting a page from a textbook. Said textbook's text is taken word-for-word from the Codex.
* Played with in ''VideoGame/SidMeiersAlphaCentauri'' and ''VideoGame/{{Civilization}} IV'', where every single technological advance, facility and secret project is accompanied by a quote from either a real book, or in the case of the former, a book, interview, memo, or famous work, real or fictional.
** In the Designer's Notes of ''Alpha Centauri'', Brian Reynolds said that Creator/FrankHerbert was his favorite science fiction author and cited ''The Jesus Incident'' as "the most important influence on the story of Planet".
** The ''Alien Crossfire'' expansion pack adds Progenitor quotes in their [[StrangeSyntaxSpeaker strange syntax]].
--> Humans : there is no space inside rocket. Progenitor : space exists around all things with mass. Space : "here". Inside rocket : "there". Secret: bring here to there.
* The Pokédex, which is devoted to providing information about ''Franchise/{{Pokemon}}'', such as appearance, attributes, and locations. Though, it's vague whether or not the entries read in-game are meant to be excerpts or the full thing. Also, some of the entries are likely made on the spot by the device in-universe, such as with Legendaries, whose abilities are not exactly common knowledge among Poké-experts except as folklore.
* In ''VideoGame/DemonsSouls'', ''VideoGame/DarkSouls'', and ''VideoGame/{{Bloodborne}}'', [[PlayingWithATrope there's no formal encyclopedia,]] but a sufficient collection of items can serve the same purpose through [[StoryBreadcrumbs item descriptions,]] encouraging players to [[GottaCatchThemAll collect everything that's not nailed down]] for the insight it gives into the setting, even if it's not compatible with their build or [[JokeItem just plain useless]] gameplay-wise.
* The Logbook scans in the ''VideoGame/MetroidPrimeTrilogy''.
* When the player accesses the mission objectives screen in the ''Franchise/AlienVsPredator 2'' game, they are also presented with short excerpts from the "incident report" compiled by [[MegaCorp Weyland-Yutani]] after the end of the game. It is both used as an atmospheric framing device, and a way of including subtle {{foreshadowing}} - for example, in the mission where the Predator first appears, the report excerpt categorically states that despite the insistence of certain parties, there was no physical evidence of the involvement of a third species. Also, each level in the game begins with a timestamp, such as "Incident minus two days," "Incident plus three weeks," or the ominous "Incident Start."
* Many of Creator/{{Infocom}}'s ''VideoGame/{{Zork}}'' computer games feature the Encyclopedia Frobozzica.
* Each "act" of ''VideoGame/TechInfantry'' has an epigraph quote either from a real or in-universe fictional work of literature, poem, song lyric, or a pithy quote from an in-universe fictional character. The title of each "episode" (four acts) is taken from the epigraph to the last act of that episode. Which means the episode title, and by extension the fourth-act epigraph, is chosen before anything beyond act one of that episode is written.
* Historical quotes in ''VideoGame/CallOfDuty''.
* Imperial slogans on the main menu of the ''VideoGame/DawnOfWar'' games.
* The quotations on the death screen in ''VideoGame/OperationFlashpoint'', such as "War is not nice - Barbara Bush".
* A not quite known puzzle-strategy (yeah) ''VideoGame/{{Netstorm}}'' had an extensive manual with in-universe quotes used as epigraphs.
* "Avoid taking drugs, it ruins you." from ''VideoGame/LittleFighter2''.
* The information screens in ''VideoGame/AgeOfMythology'' were full of these.
* The loading screens of the later ''VideoGame/TotalWar'' games (''[[VideoGame/RomeTotalWar Rome]]'' and ''[[VideoGame/MedievalIITotalWar Medieval II]]'') have these. Plus in ''[[VideoGame/ShogunTotalWar Shogun]]'' there's a philosipher in the throne room, who if clicked on gives you random quotes from ''Literature/TheArtOfWar''.
* ''VideoGame/{{BioShock|1}}'' has quotations by its own characters during loading screens.
** Nearly all of which you can find a [[ApocalypticLog recording]] of in their original context at some point in the game.
* ''VideoGame/StarOceanTillTheEndOfTime'' and ''VideoGame/StarOceanTheLastHope'' feature an in-game Dictionary, which is updated with new entries as the story progresses and terms are brought to light. They are even categorized by topic, such as "Planets", "Technology", "Species", and so forth.
** In the former's case, you know you are in for a serious MindFuck when you open the dictionary before electing to talk to anyone and it contains entries on quantum physics.
* ''VideoGame/FinalFantasyXII'' has an expansive bestiary which hold theories and information about the various monsters, people and Espers the party defeat in their travels. In addition, killing enough of the specific types of wild encounter uncovers additional information about the places in Ivalice, and sometimes about rare items that certain enemies randomly drop.
* ''VideoGame/VagrantStory'' opens with a quote from famed historian [[VideoGame/FinalFantasyTactics Alazlam Durai]], author of ''The Durai Papers: 400 Years of Truth''.
* ''VideoGame/FinalFantasyXIII'' takes this a step further--the datalog mixes entries like this in with AllThereInTheManual.
* The Compilation of ''VideoGame/FinalFantasyVII'' has the play ''Loveless'' which is incredibly popular in-game. ''VideoGame/CrisisCore'' references it most often though it makes [[WhatDoYouMeanItsNotSymbolic less]] [[TrueArtIsIncomprehensible sense]] than it had in the original game.
* The Church Of The New Epoch's mission briefings in ''VideoGame/{{Syndicate}} Wars'' include quotes from their religious text.
* ''VideoGame/InFamous'': the major story divisions through the game come with quotations from various historical figures.
* Several characters in ''VideoGame/FinalFantasyIX'' are theater buffs. One particular fictional play, ''I Want To Be Your Canary'', has particular symbolic importance to the plot, and a few characters quote it during plot sequences.
* The whole ''VideoGame/{{Warcraft}}'' oeuvre, especially the trading card game, uses fictional quotes from various plot-important characters to tie the whole expanded universe together.
* Both playable races in ''O.R.B: Off-World Resource Base'' consider an ancient document called the Torumin their Bible, some parts of which are quotes in the game.
* In the ''Franchise/DragonAge'' series, the player finds parchments with fictional poems, stories, and legends scattered throughout Thedas. All of these are logged into the respective game's EncyclopediaExposita along with game-relevant information.
** Bioware's earlier game ''VideoGame/JadeEmpire'' does something similar.
* ''VisualNovel/{{Snatcher}}'' does this with a supercomputer that contains a lot of information about the game world.
* In ''VideoGame/DeusEx'', there are several books and newspapers that the player can read.
* In VideoGame/ValkyriaChronicles, the entire game is setup like a history book that is divided with tabs that contain the main story and recorded entries about characters and weapons.
* ''VideoGame/DiabloIII'' contains a wealth of lore on monsters and the world that can be discovered in-game through lore entries. The two most frequent authors of such are Deckard Cain [[spoiler:who dies early in game at the hands of Maghda]] and Abd Al-Hazir [[spoiler:who it's implied met a similar fate at the hands of Magdha's coven in Caldeum after witnessing a particularly gruesome ritual]].
* ''VideoGame/TheWitcher'' features a codex similar to ''Mass Effect'' and ''Dragon Age'', tailored to the needs of a professional monster hunter. It gives geopolitical and historical details, [[MonsterCompendium how to kill monsters]] and [[TwentyBearAsses what components can be harvested from them]], and a list of major characters Geralt meets in his travels.
* The ''VideoGame/{{X}}-Universe'' games have an in-game encyclopedia of game objects, corporations, governments, trade goods, and the like. Almost everything in the game has a little bit of history behind it - viewing the info for the Dragon corvette will talk about the Dragon Incident that nearly destroyed the prototype and the station it was housed in, for example.
** The Encyclopedia returns in ''Videogame/XRebirth'', which seems to show it as being something like Wikipedia - Ren Otani modifies several entries (about the ''[[SuperPrototype Albion Skunk]]'') until he reaches one that has been locked by the [[MegaCorp Plutarch Corporation]] [[OneNationUnderCopyright government]].
* ''VideoGame/{{Syndicate}}'' (2012) has an infobank, which gets updated every time you encounter a relevant item.
* ''VideoGame/XCom'' has the [[MonsterCompendium UFO-pedia]], which updates whenever your research of your enemy's units and technology (and ''your'' units and technology) makes an advance. For the most part it is fluff, but some information is tactically (and story-wise) relevant. Some other ''X-Com'' clone games (''VideoGame/UFOExtraterrestrials'', ''VideoGame/{{Xenonauts}}'', ''VideoGame/UFOAfterBlank'') sometimes provide additional info about the setting on their UFO/whatever-pedias as well.
* The ''VideoGame/CrystalCaves'' story section consists of "entry # 981,231,783,813,651" from the "Galactic Encyclopedia", which briefly describes the protagonist and his quest for riches.
* ''VideoGame/NosferatuTheWrathOfMalachi'': Father Aville's Encyclopedia Of The Undead.
* ''VideoGame/VictorVran'' has the Codex, which is mostly an ingame manual (it describes the different weapons' attacks, the crafting recipes, etc.), but it also includes descriptions of monsters (including bosses) written as they were notes from Victor's diary; those entries appears when Victor kills one for the first time.
* In ''VisualNovel/RisingAngels'', short database entries on various basic elements of the setting (countries and species, mainly) are available.

* Hardwick and Little's ''Bestiary'', ''Webcomic/GunnerkriggCourt'', Chapter 3.
* Webcomic/{{Parallels}} has ''[[http://www.mightymartianstudios.com/2012/11/09/ch1-001-reference-works/ Encyclopeida Unversalis]]''.
* Most of ''Webcomic/MarauderShields'' strips come with one or two Codex entries deliberately styled after the original ''VideoGame/MassEffect3''.
* ''Webcomic/{{Drive}}'' has the ''Enciclopedia Xenobiologia'', written from the human perspective and thus occasionally lacking in detail or subtly wrong.
* Used sometimes as filler in Webcomic/{{SSDD}}, giving information of the setting and sometimes explaining minor FridgeLogic. Among the quotes used are quotes from various characters including [[spoiler:(future)Norman Gates]], excerpts from ''A Rough Guide to The Anarchist and the Collective'' from Eric King, excerpts from MIT lectures, magazines, etc. All of them fictional.
* Between and halfway through the chapters of ''Webcomic/StandStillStaySilent'' author always puts some documents from in-universe, such as maps, Cleansers' recruitment poster, writing of the various nationalities of the world and so on. It's very helpful, as the story itself rarely drops an InfoDump.

* In the Literature/WhateleyUniverse, the author of the Phase novels often does this, with quotes from rock songs as lead-ins for chapters. But the quotes are usually from the fictional band Brass Monkey, so they can be as relevant as the author wants.
* Used in ''Literature/LookToTheWest'', which generally has the structure of an initial quote which may or may not be relevant to the rest of each chapter, and then the main text also supposedly extracted from in-timeline books. Occasionally inverted with the starting quote being taken from our own world's history.
* In ''Guild of the Cowry Catchers'', the quotes beginning each episode are from a pair of books by the HeroAntagonist and leader of the titular LaResistance.
* Go type about:mozilla in the URL box in any Mozilla browser from Netscape Navigator 1 all the way up to the current version of Firefox. (Original Web? Not exactly, but close enough.) Or just google "Book of Mozilla".
* Each chapter of the various campaign archives from The ''Roleplay/GlobalGuardiansPBEMUniverse'' began with quotations from some in-universe source. While most of these were off-hand (yet relevant) comments from the characters involved about the action presented in the chapter, sometimes they were quotations from such items as ''An Examination of Irregular Wave Forms and Power Phasing Effects in the Jaffe Battery'' (better known as the "Ray Gun Paper"), ''Genetic Inflexibility and Geographic Isolation as Influences in Metagene Frequency'' (a scientific study on why certain regions of the world have more superhumans than others), and ''The Book of Holy Power''. the religious scripture of the Church of Jesus Christ, Superhuman (a cult that teaches that Jesus was a Metahuman who will one day return from his "sojourn" with an advanced alien society somewhere in space).
