The African American Biographical Database has two search options: Search Profiles and Search Full Text. You must select one to search; the collections are not cross-searchable.
Once you have selected the collection you wish to search, enter search query terms and data and click the Search button (circled in both images below) to retrieve results.
See the Profiles Results or the Full Text Results pages for more information about the results pages specific to each collection.
