The Women's Library @ LSE is Britain's main library and museum resource on women and the women's movement, especially concentrating on Britain in the 19th and 20th centuries. It has an institutional history as a coherent collection dating back to the mid 1920s, although it has existed under several different names, different parent bodies, and in different locations. Since 2013, the library has been in the custody of the London School of Economics and Political Science, which manages the collection as part of the British Library of Political and Economic Science in a dedicated area known as the Women's Library @ LSE.
