The Institute amassed a unique archive on the 1918 German Revolution.

Evidence

There was a special library, which in 1928 contained approximately 37,000 volumes, 340 scholarly journals and thirty-seven German and foreign newspapers. There was a reading room which, in the same year, was used by more than 5000 people. There was an archive which, as Pollock described it in a prospectus for the Institute published in 1930, contained a collection of documents on the history of the 1918 German Revolution and on events significant for the labour movement in the succeeding years, which is today already unique of its sort', and in which countless leaflets, posters, appeals, circulars, reports, letters, photographs, etc.’ had been collected. — Rolf Wiggershaus, The Frankfurt School, 107
