Bonus strips added when a comic or Web Comic is published as a book. A Sub-Trope of Bonus Material. See also Side-Story Bonus Art.
Examples:
Comic Books
- X-Wing Rogue Squadron: There is a new extra comic included in one of the Omnibus collections, about Wedge being a Destructive Savior and Luke defending him from angry townspeople.
Comic Strips
- Calvin and Hobbes: Several collections are prefaced with bonus stories and poems done in watercolor:
- The Essential Calvin & Hobbes had the story poem "A Nauseous Nocturne."
- The Indispensable Calvin & Hobbes had several short poems.
- The Authoritative Calvin & Hobbes had a story in which Calvin, while doing his homework, decides to boost his memory by transmogrifying himself into an elephant.
- The Calvin & Hobbes Lazy Sunday Book had a story in which Spaceman Spiff fights a Booger Being (Susie Derkins) and a Naggon (Calvin's mom).
- The Tenth Anniversery Collection had author commentary next to each strip.
Manga
- Daily Lives of High School Boys is published in a free-for-view commercial online anthology that operates like traditional Japanese Anthology Comic. However, it is collected into printed volumes, additional skits, i.e. High School Girls are Funky, were added. It is remarkable to note that High School Girls are Funky is the only thing in this series that has a long-term plot.
- I Think Our Son Is Gay: When transforming it from webcomic to print, Okura adds one page to the end of each chapter, which continues with the rest of the chapter. He also draws some print-exclusive chapters, such as Chapter 20 and 21.
Webcomics
- The Adventures of Dr. McNinja: The first book has Alt Text (first introduced in the second issue) added for the first issue. The third book has a short story starring the side character "The Beeman".
- Axe Cop: The book, in addition to publishing every episode of the webcomic released up to that point, includes commentary from Ethan on the Ask Axe Cop strips, plus fanart.
- Ctrl+Alt+Del:
- The various print volumes contain commentary notes for various strips as well as various wallpapers and other artwork. The composition of the speech bubbles are also redone.
- The 1.0 10 Year Box Set contained the above, but also featured an epilogue to the original ending that shows Ethan wind up in the distant future, where Zeke is a robot-kind ambassador Lucas is a prominent game developer and since deceased, and Lilah has moved on from Ethan, but they remain firm friends. As well, all the subscriber-exclusive comics were included (some of which expand or foreshadow the normal strips), and the strips were sorted so that the core storyline could be read in sequence.
- Girl Genius: Some of the collected editions have extra story pages, to clarify details and/or to make sure that the big double-page spreads end up on facing pages.
- El Goonish Shive: Both books have an additional silly story and a Post-Episode Trailer.
- Henchgirl: The trade paperback has bonus stand-alone comic strips featuring many of the characters, alternate cover art, and a selection of fan art.
- Housepets!: One book features an entire short story accompanied by some original art, All The King's Men, adding more information about King's first weeks as a dog. The story was actually part of a contest where Rick Griffin wrote the first part and invited his readers to finish, with the winner being published.
- Let's Speak English: An extra comic about Mary's first meal back in America, commentary on all the comics, and additional info about life in Kurihara.
- Ménage à 3 and its spinoffs, Sticky Dilly Buns and Sandra on the Rocks, always include a few extra story strips in the print collections, generally filling in some side-details of the main plots.
- The Order of the Stick: Dungeon Crawling Fools has a set of new comics introducing the characters better than the cast page on the website. Lampshaded in-story twice. Once when characters suggest they add an unseen bit of action as bonus content for the next book and when Haley is suffering under a speech impediment that turns all her speech into cryptograms, she can still communicate with The Oracle. When asked, he says that no, he doesn't understand her - he just has the power to look into the future, for when the strips are released in book form with translations attached. The strip has also had a parody lampshading after a character was sent to a particularly stupid offscreen waiting room, The Semi-Elemental Plane of Ranch Dressing:
Belkar: Hey, maybe we'll see that as a bonus story in one of the later books!
Vaarsuvius: Maybe we will never mention it again. - Pandemonium Wizard Village contains a short extra chapter in the second volume about a young Domika and Kayoh sneaking into Mayor Ainu's art studio.
- Penny Arcade collections include author commentary from strip author Jerry Holkins, select newspost reprints that provide either additional insight into the strip or entertainment, and the occasional artwork or even whole strips that were either unused, unavailable or only shown in the posts.
- Sam & Fuzzy has an extra story and some Skull Panda strips in its first mini-book, and probably similar in the newer ones, but I haven't read them.
- Schlock Mercenary: All but one of the books contains a bonus story. These mostly serve to fill in the backstory for some of the characters (in particular Schlock himself) or form an epilogue showing what happened to some of the secondary characters after the main plot of the book.
- Sleepless Domain: Volume 1 contains info about the conception of the comic and early concept art of Team Alchemical.
- Sluggy Freelance: The collected volumes
contain these. The character of Deplora was actually introduced in one of these bonus stories before being brought into the main strip.
- Tea House: It lures potential readers by promises of yummy mansex, traps them with a captivating plot, and rakes in the chips by keeping the great majority of the smut as well as some extra strips print-only.
- Whats Up Beanie has quite a few comics not on the website:
- The Framing Device of the book is Baby Beanie coming to the future to see how Adult Beanie is doing.
- Beanie's first move to New Zealand and subsequent adjusting to a new school and learning to speak English.
- Beanie and Mike meeting, falling in love, getting engaged, and then marrying.
