offprint - An excerpt of a larger publication which has been printed and bound separately for promotional purposes. For example, publishers will print and bound a chapter of a book to send to booksellers or for the author to give away before the entire book is published. Scholarly excerpts are another example; a portion of a large journal piece printed for a professor to distribute. Offprints are highly sought after by collectors because, technically, they can be considered a first separate edition of the work and will often have a presentation inscription.
