Accessible online at http://plre.folger.edu and searchable in a variety of ways, PLRE.Folger, a project of the Folger Shakespeare Library in Washington, D.C., is a database that consists of 1) all the annotated book-lists that appear in the published volumes of PLRE and 2) selected book-lists that have been published elsewhere.

This second group of previously published book-lists (appended book-lists) are identified in the database with Ad prefixed to the PLRE number. They are not completely re-edited but are augmented as necessary (e.g., by the provision of uniform titles, PLRE reference numbers, subject categories, and the like) so that they conform to the PLRE format and are subject to retrieval with other entries.

In addition to all the information found in the published volumes of PLRE cited above (with the exception of the biographical introductions), PLRE.Folger contains for each book listed: the dates, profession or vocation, and social status of the person associated with the book-list; the purpose of the manuscript containing the book-list (whether, for example, it was a will, an inventory or a receipt); the location in England where the manuscript was drafted and its date; the manuscript’s current location; and one or more classifications defining the subject categories of the work.

Thus far, these appended lists add thirty book-lists containing approximately 1000 books to those appearing in the published volumes. As of January, 2009, PLRE.Folger consists of 196 book-lists containing a total of 12,997 books.
