Spinnboden - Archive for the Discovery and Preservation of Woman Love, or simply Spinnboden, is a project created by the lesbian group Homosexual Action West Berlin in 1973 for the purpose of archiving lesbian history. 

Today, Spinnboden is Europe's oldest and largest lesbian archive. Spinnboden hosts events and bookclubs, and allows people to borrow their archives of books, magazines, and other materials to aid academic research.
