This dissertation explores the management and development of libraries at women’s colleges in Oxford This study examines the colleges established for women students between 1879 and 1920: Lady Margaret Hall, Oxford; Somerville College, Oxford; St Hilda’s College, Oxford; and St Hugh’s College, Oxford. These colleges were founded to allow women to study in Oxford, but women were not permitted to become members of the University of Oxford until 1920. Consequently, most of the academic provision for students, including library access, was provided by colleges and the Association for Promoting the Education of Women. This study analyses contemporary documentary evidence to learn how the libraries were staffed and their collections developed, allowing us to gain a greater understanding of the history of women’s college libraries.
