About the APS Digital Library
The APS Digital Library provides access to a wide variety of digitized items from the holdings of the American Philosophical Society.
Many of the items in the Digital Library can be viewed with additional context by using our Collections Search, and viewing manuscript finding aids.
Some of the collections have access restrictions.
The APS strives to increase access to all of our holdings. Some of our holdings, however, represent cultural or other types of sensitivity.
Our audio material is available only via login. For more information, please see our help page on audio access.
All of our holdings are available on-site.
