Curious about the other half of the Science History Institute? Step into the Othmer Library of Chemical History!

Since its founding in 1988, the Othmer Library at the Science History Institute has been a haven for research in the history of science—but there’s more to the story. Explore the reading room on a guided tour, learn how our collection has grown, and discover why we have one of the most comprehensive rare book collections on chemistry and its alchemical roots.
