The 'What They Saw' anthology presents historical photobooks by women in the broadest sense possible: classic bound books, portfolios, personal albums, unpublished books, zines and scrapbooks. Some of the books documented are well-known publications such as Anna Atkins’ Photographs of British Algae: Cyanotype Impressions (1843-1853) and Diane Arbus: An Aperture Monograph (1972), while other books may be relatively unknown, such as Alice Seeley Harris’ The Camera and the Congo Crime (c. 1906).
