Comprises a series of diaries and private journals kept by Bartholomew between 1904 and 1925 giving a detailed record of his daily life, social engagements and friendships, aspects of his work at the University Library, progress of various literary projects, plays attended and important books that he read. The entries during the last dozen years covered by the journals show Bartholomew as increasingly preoccupied by real or imagined health problems, and subject to fits of depression and anxiety. The collection also includes a commonplace book, 1904-1932, various portrait photographs and three printed books.
