The Donald F. and Mildred Topp Othmer Library of Chemical History is an independent research library encompassing the history of chemistry and related sciences and industries.

The Othmer Library was founded in 1988 when Donald and Mildred Topp Othmer announced their challenge grant to be given for the creation of a library that would work to preserve the history of the chemical sciences. The library now houses more than 150,000 print volumes, rare books and manuscripts, archival materials, and historical photographs. Together these collections—spanning nearly six miles of shelves—form an unrivaled resource for the history of chemistry and related sciences, technologies, and industries.
