In addition to the collections of Spencer, Crawford, Christie and Bullock, holdings have been enriched by gifts, permanent loans or purchases of several libraries belonging to institutions and individuals. These include the French Revolution Broadsides donated by the 27th Earl of Crawford in 1924 and the archives of the Methodist Church of Great Britain in 1977. In 1924 the library purchased the greater part of the French revolutionary collection of the Bibliotheca Lindesiana; and then on the occasion of the library's semi-jubilee the 27th Earl of Crawford donated the French Revolutionary Broadsides from the Bibliotheca Lindesiana. Between 1946 and 1988 a number of sections of the Earl of Crawford's library were deposited here, however all but one of these were withdrawn in 1988.
