Academic and scholarly publication
In scholarly and academic publishing, scientific and non-fiction books that are released serially (in successive parts) once a year, or less often, are also called a series. (Publications that are released more often than once a year are known as periodicals.) The connection among books belonging to such a series can be by discipline, focus, approach, type of work, or geographic location. Examples of such series include Antwerp working papers in linguistics; Early English manuscripts in facsimile; Garland reference library; Canterbury Tales Project; Early English Text Society.
