A large collection of bookplates, Scottish, English and colonial, mounted in 40 volumes, with another 40 volumes of books about heraldic bookplates, bequeathed by Dr John Henderson Smith of Harpenden (1875-1952), and received in 1953. Henderson Smith was a member of the Ex Libris Society which lasted from 1891-1908, and served as the Secretary of the Bookplate Exchange Club for forty-seven years (1901-48). Other smaller collections of bookplates which have been acquired include the Culley (one vol.), the Stitt (three vols.), and the Lamb (23 vols.) collections, the latter including many foreign bookplates and labels of Scottish circulating libraries.
The Henderson Smith collection has a slip catalogue of the bookplates arranged alphabetically under the names of owners, with brief descriptions of the bookplates.
