The fonds consists of 2,484 items, nearly all of which are photocopies of articles, documents, correspondences, photo groups or artwork that the donor has acquired from various magazines, newspapers, books, associates and other archives and libraries. The vast majority of the collection relates to “Lost Horizon”, with a much smaller, though still significant, percentage relating to "Helen of Troy". Over 150 of the items fall outside the scope of either of the two aforementioned movies, being a collection of writings, photographs and artwork relating to Hollywood and the movie industry in general, as well as California travel information and info on Tibet. The fonds is divided into the series “Lost Horizon” articles, “Lost Horizon” documents and research, personal effects, "Lost Horizon” publicity stills, “Lost Horizon” production photographs, “Lost Horizon” negatives, “Lost Horizon” art, “Helen of Troy”, related interests, oversized items and "Lost Horizon" microfilm. The "Lost Horizon" articles series contains newspaper, magazine and journal articles, as well as book excerpts, related to various "Lost Horizon" subjects, such as production, reception and cast and crew biographies. The “Lost Horizon” documents and research series contains various primary sources such as interviews, scripts, theatre programs and legal documents. The personal effects series contains content related to Ely Bronstein’s personal life such as correspondences and ephemera, though the vast majority of this material relates to “Lost Horizon”. The next two series contain photographs of “Lost Horizon”, both publicity stills – scenes from the movie blown into photos – and production photos – pictures taken of the production processes or of members of the production crew. The negatives relating to “Lost Horizon” are reproduced photographic negatives, while the artwork contains movie posters and concept art. The “Helen of Troy” series contains material relating to that film, including articles, documents and publicity stills. The related interests series contains various articles and pictures related to Hollywood and the movie industry, as well as information about California and Tibet. All oversized items requiring larger boxes are included in the oversized items series. Lastly, the "Lost Horizon" microfilm series contains pressbooks and visual representations of the film on 35mm microfilm. The items are all paper photocopies of their original formats, with the exceptions of a few original correspondences, a few original newspaper clippings, the negatives and the microfilm.
