In the 1990s, "trade paperbacks found their popularity boom". Comic book publishers began releasing trade paperbacks of collected story arcs directly after those stories' original periodical publication, because a new reader could purchase the trade paperbacks and access the entire series' stories to date. The Librarian's Guide to Graphic Novels for Children and Tweens by David S. Serchay explains: "At first it was the most popular stories that were being collected, but more and more comic book stories are now being put into trade, sometimes less than two months after the 'newest' issue is sold. And [...] not only recent material but a great deal of older material is finally being collected into trades". In 2015, Polygon highlighted that "though this was far less common a decade ago, pretty much every monthly comic out there right now is eventually collected into trade paperback or hardcover edition that prints several issues in one package".
