There’s an important overview of the location and status of Alla Nazimova’s papers and other research assets on Columbia University’s Women Film Pioneers Project, written by Jennifer Horne, including this bit:

There is no denying the intriguing power of a biographical narrative that traces connections between Alla Nazimova and almost every prominent lesbian in Hollywood, as well as gay male cultural icons such as Oscar Wilde, Rudolph Valentino, and Montgomery Clift, and ends with a penniless and ill Nazimova a tenant in the Los Angeles hotel she once owned. But the archival materials that have been collected over the years suggest that much more can be made of Nazimova’s life as performer, both on screen and off.

The personal correspondence and writings that constitute the Nazimova Papers at the Glesca Marshall Library in Columbus, Georgia, have not as yet been cataloged. The extensive collection of copyrighted publicity stills and family photographs, postcards, letters, and newspaper clippings at the Library of Congress in both the Kling-Lewton Papers and the Harry E. Vinyard, Jr., Papers offers to researchers a fragmented but illuminating documentation of the devoted following Nazimova’s celebrity attracted over the course of her career.
