A Collection of books and other printed material on "The Great War and Associated Conflicts" known as "The Russell Cawthorn Collection".
The Collection has its own database, which can be accessed via The 1926 Foundation web-site but all the books in the Collection are also categorised in St. Andrews University Library's own database, SAULCAT. In order to access a particular book on a particular subject, the Foundation's own database is almost certainly the place to go to.
