In 1953, two bibliophiles, Eddie (Edmund) Frow and Ruth Haines, met at a Communist Party Summer School.

In 1956, they set up home together and the merger of their book collections was the beginning of the Working Class Movement Library.

In 2007, the relationship changed when the trust took full responsibility for the housing and staffing of the collection with the council providing a lease of the building and an annual financial grant.

The WCML houses 30,000 books as well as journals, newspapers, pamphlets, leaflets, banners, pottery, photographs, personal papers, archives of organisations, trade union emblems, badges and other artifacts.
