In academic publishing, an eprint or e-print is a digital version of a research document (usually a journal article, but could also be a thesis, conference paper, book chapter, or a book) that is accessible online, whether from a local institutional, or a central (subject- or discipline-based) digital repository.
When applied to journal articles, the term "eprints" covers both preprints (before peer review) and postprints (after peer review).
Digital versions of materials other than research documents are not usually called e-prints, but some other name, such as e-books.
