For other lists of sources, which may be useful for family historians, see the bibliography.

If you are unable to find any of the listed books, you can look them up when you come to The National Library of Wales. Most of them are accessible through the online catalogue. If not, you are advised to search the microfiche catalogue at the Library. Some of the titles may also be found on the open shelves in the Library's reading rooms. Please note that you need a valid reader's ticket in order to request or consult any materials which form part of the Library's collections.
