Recent research has greatly increased both the kinds and amount of evidence available to document the ownership of books by early modern women. Much of this new evidence derives from increased attention to ownership markings in surviving early modern books and from the ongoing discovery and editing of manuscript booklists. Booklists of various kinds represent our most comprehensive means of access to the books early modern women owned. The Private Libraries in Renaissance England (PLRE) project now enables searches of eighty booklists associated with early modern women, comprising about 2000 edited records of book ownership. The project is ongoing, and additional lists, including substantial ones, are in progress. Preliminary research using this database has begun to provide an evidential basis for generalizations about women’s reading and book ownership in the period, confirming some longstanding assumptions but also challenging others.
