Bonus strips added when a comic/Web Comic is published as a book. A Sub-Trope of Bonus Material. See also Side Story Bonus Art.
- The first The Adventures of Dr. McNinja 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".
- The Order of the Stick books tend to do this (not counting the two print only stories). For example: 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.
- Several Calvin and Hobbes 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.
- Sam and Fuzzy had 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.
- Some of the Girl Genius 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.
- There is a new extra comic included in one of the X-Wing Series Omnibus collections, about Wedge being a Destructive Savior and Luke defending him from angry townspeople.
- Both El Goonish Shive books have an additional silly story and a Post-Episode Trailer.
- The Sluggy Freelance collected volumes contain these. The character of Deplora was actually introduced in one of these bonus stories before being brought into the main strip.
- The Axe Cop 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.
- Tea House does cleverly: it lures potential readers by promises of yummy mansex, traps them by a captivating plot, and rakes in the chips by keeping the great majority of the smut as well as some extra strips print-only.
- Daily Lives of High School Boys is not strictly a webcomic; it is published in an free-for-view commercial online anthology which operates like traditional manga anthologies. However, like the examples above, when this free-to-view online manga 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.
- Homestuck has the author's commentary at the bottom of each page.
- 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.
