Mann Library holds historical primary sources on a variety of topics related to life sciences, agriculture, applied social sciences and human ecology. A growing number of selections from our rare and distinctive (RAD) collections are available online as digital collections. Many are presented as part of virtual exhibits. Many more are available through Cornell University Library's (CUL) Digital Collections portal. In the tabs of this guide, you will find these kinds of online primary sources from some of Mann Library's areas of strength as well as direction on finding more.
Information about accessing and using these primary sources onsite and in-person is available through Mann Library's RAD Collections page. Information about primary sources from CUL's collection beyond Mann Library can be found on the Digital Rare And Distinctive Collections at Cornell LibGuide.
Cornell Library also subscribes to databases of historical primary sources for its library patrons.
