New readers, and those needing to renew their Cambridge University Library card, should contact the Library’s Reader Registration Office
Email: registration@lib.cam.ac.uk or phone: +44 1223 333030 in advance of a planned visit for information about admission to the Library and to book an appointment to obtain a card. Further details and an online application form are available on the joining the library pages.
To avoid disappointment, readers wishing to consult a particular archive or manuscript are advised to contact the RCS Curator in writing or by email (rcs@lib.cam.ac.uk), giving as much notice as possible. Some collections have yet to be catalogued online, or in any detail, and it can therefore be difficult for a reading room to ascertain quickly the location of items within some collections.
