The Caird Library provides public access to the unparalleled paper-based collections of Royal Museums Greenwich. Together, the archive and library collections are the most comprehensive maritime resource in the world, holding over two million items dating from the 15th century to the present, including manuscripts, modern and rare books, journals, prints and drawings, charts and maps, and ephemera.

This specialist reference library is a rich research resource for all. Entry is via a free Reader’s Ticket which can be applied for online in advance of your first visit, or on the day. To register and to request items to view in the Library, please see Aeon and guidance on using Aeon.

To help plan your visit to the Caird Library, our online catalogues can help you identify resources that you may wish to view. See the Library catalogue, the Archives catalogue and Collections Online. A guide to your first visit to the new Caird Library is available. See also the Caird Library service statement.

Please note that although we hold lots of collections, maritime history research can be time-consuming so please allow plenty of time for your visit.
