The 'archive' consisted of periodicals: Greenham Common Women's Peace Camp News' (1 issue, 1983); pamphlets (1982-1983), ephemera including leaflets and circulars (1982-1983); Press cuttings (1982-1983), badges.

As at Jan 2009, The Women's Library held approximately 1050 posters in the Museum Collection, with c 100 posters identified in the archives.

The earliest posters held result from suffrage activities and can be divided into three main groups; advertisements for meetings and events, illustrated propaganda posters arguing why women should get the vote, and thirdly newspaper bills bearing suffrage related headlines, used to promote paper sales.

All other posters are arranged by subject and date from the 1970s to the present day. The collection represents a mixture of women's campaigning, campaigning by organisations to promote gender equality, and posters produced to advertise women-focused events and publications. There are a small number of posters that portray women's issues and campaign work internationally. The work of The Equal Opportunities Commission in England and Ireland is particularly well represented as a result of a large donation of their obsolete posters during the 1990s. Also well represented with almost 80 posters is the work of See Red Women's Workshop, a women's liberation screen-printing collective (1974-1984).

The archive consists of correspondence, campaigning material, photographs, posters, postcards and badges. It mainly relates to the Greenham Common Women's Peace Camp, but also covers international peace campaigns. It includes the manuscript of a book on the menopause.
