Thanks largely to the generosity of Fred Todd, the collection of Williams material has grown at a rapid rate since the initial acquisition in 2001. While virtually every section of the collection has been expanded, the cinema component has seen exceptional growth. Almost two hundred new film stills and off-camera shots have been added, along with more lobby cards, posters, and a press packet for the 1973 ABC television version of The Glass Menagerie starring Katharine Hepburn. The theater section has grown as well with the addition of new playbills; a fine set of photographs by Eileen Darby of Jessica Tandy, Uta Hagen, Vivien Leigh, and Judith Evelyn as Blanche in A Streetcar Named Desire; and a playscript from the original production of Streetcar that belonged to Irving Schneider, an associate producer.
