Consists of material collected by Kitty Haas including items regarding the writer, publisher, artist, and philosopher Elbert Hubbard, as well as the reformist community he founded of craft workers and artists, Roycroft. The collection contains advertisements and broadsides, ceramics, correspondence, newspaper articles, photographs and sketches, and printing press records. Also included are original manuscripts, typescripts, and notes of Hubbard's, a framed portrait from the Boston-based Bachrach photography studio, and materials related to Hubbard-contemporary printer, artist, and type designer, Frederic Goudy. Notable topics include Roycroft Press publications The Philistine and The Fra, subscriptions and sales of Roycroft crafts and publications, Elbert Hubbard's personal life, and the sinking of the RMS Lusitania.

The collection also contains papers documenting Kitty Haas's personal and professional life, including fliers advertising Haas's shops, photographs of Haas and her store, and nineteenth-century Viennese portraits, most likely of Austrian relatives of Haas. Some of the Roycroft materials appear to have been gathered by Simeon Braunstein, a friend or partner of Haas, who features prominently in the correspondence.
