Can I use the National Library of Wales?

Yes, you may register for a National Library of Wales (NLW) Reader's ticket to gain access to their collections. You can register online to start the process of becoming a reader before your visit. This will make it easier and quicker when you visit the NLW in person. Tickets are valid for a period of 3 years.

Please bear in mind that in order to gain a full reader's ticket you must take along with you 2 proofs of identity, one of them showing your current address.
