Monographs are academic books written on an aspect of a subject or a single subject, typically aimed at, but not restricted to, a scholarly audience. However, most of the titles used in the project are single-authored, but some are multi-authored; others are closer to edited samples. Discipline has an impact – in some disciplines, it is relatively common to produce multi-authored monographs, while in others it is rare.

Open Access project uses ‘monographs’ as a shorthand term to comprise publications including monographs, but not limited to monographs collections of articles by one or many authors, and scholarly editions of texts.
