Our databases have articles which you can use for biographical, contextual, and historical information on your topic.
You can always start your research with LibSearch, which searches many of our databases at once. In order to concentrate on finding more specific material on your philosopher, you can also search any (or all) of the databases listed below. But first, please watch this video, that explains how to search databases.
Remember to create a list of "search terms" and use the "limits" (by date, peer-reviewed journals, etc.) provided by databases.
