In academic publishing, reprints are bulk reproductions of individual articles previously published in academic journals. Reprints from scientific, technical, and medical (STM) journals are used by researchers in some fields to generate awareness among audiences who don't subscribe to the journal e.g. physicians, consumers, investors etc. Reprints are usually ordered directly from the publisher of the journal. However, some third-party service providers also exist, serving as an intermediary that provides a single source of reprints from multiple publishers.
In collectible card games, a reprint is a card published in an earlier card set which is published again in a new card set. Often, the art on the card may be changed, or the text updated to reflect new errata.
Publishers will reprint classic comic books from years or even decades ago, often restoring the art with newer techniques. The reprints may be standalone comic books, compilation trade paperbacks, or back-ups in other comic books.
Comic books which sell out may be given a second (or more) printing in order to bring more copies to the distributor.
