Book Owners Online is a directory of historical book owners, with information about their libraries, and signposts to further reference sources. It currently covers seventeenth-century English owners, with the potential to be expanded.

The database is a development from David Pearson’s listing of English book owners of the sixteenth and seventeenth centuries available on the Bibliographical Society’s web site.

Book Owners Online has been developed by the Centre for Editing Lives & Letters at UCL with funding from the Society and the Bodleian Library.

The database can be consulted at https://bookowners.online/. See also http://www.bibsoc.org.uk/content/book-owners-online.
