With the acquisition of the Provine collection in 2013 we became the repository of the largest history of science collection in private hands

With 100k offprints from the 1880's to approx 1890's our collection contains many of the highlights in Cytology, Genetics, Evolution, Reproduction, Eugenics, and Molecular Biology. It is the largest such collection offered today by any dealer worldwide.It rivals many  of the collections held in institutions.
