Legacies of Eugenics project banner

The careful study of original documents is key to all historical investigations. Digital libraries offer many primary sources associated with the history and legacy of eugenics.


In the Legacies Digital Library, we provide material we find otherwise difficult to locate. These are available as open access, free to download pdf files under CC-BY-NC license.




Publication of this material online is done strictly for historical and academic reasons. The work of eugenicists was pervaded by racial, ethnic, gender, and ableist prejudice. Readers must be alert to these biases in this material.


Reproduction of this work here is not an endorsement or promotion of the views expressed or eugenics in general. Quite the reverse. All articles are published in full, except where necessary to protect individual privacy. We believe there is a clear academic interest in making this historical material more widely available.
