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";[1] "Early English Manuscripts in Facsimile" (Rosenkilde & Bagger, Copenhagen);[2] Garland reference library; "Canterbury Tales Project" [3] (see The Canterbury Tales); Early English Text Society.
The Library of Anglo-Catholic Theology (a series of 19th-century editions of theological works by Church of England writers, devoted to significant Anglo-Catholic figures,[4] published by John Henry Parker) is an example of a common usage in naming monographic series; another example is the John Harvard Library which consists of notable works relating to the United States.
In many cases each volume in such a series itself contains individual chapters or articles written by different authors, usually on the same general theme.
Each of these volumes contains "a selection of articles by a leading authority on a particular subject ... reprinted from a vast range of learned journals, Festschrifts, conference proceedings ...".
