The National Library of Wales, also known as The Nation’s Memory, is dedicated to collecting, preserving, and providing access to Welsh history and culture. With over 6 million books, 40,000 manuscripts, and 1. 5 million maps, their collections are vast and diverse.

As a Legal Deposit Library, they have the privilege of a copy of every book published in Britain. While their main focus is on items related to Wales and the Celtic countries, their collections extend beyond these boundaries. Visitors can explore their collections by searching their extensive catalogues, which include the Main Catalogue and the NLW Archives and Manuscripts Catalogue.

In addition to their physical collections, the National Library of Wales offers digital exhibitions, allowing users to immerse themselves in items such as the White Book of Rhydderch or early photographs of Wales. To access the collections, individuals can become readers and register to use the Reading Room. The library also provides an Enquiries Service, where visitors can receive assistance with searching and using the collections.

By making a donation, individuals can support the library in preserving and expanding the nation's memory for future generations. Located in Aberystwyth, the National Library of Wales welcomes visitors and offers a range of services, including exhibitions, events, and a shop
