The listed books below are only general reference materials. If you already know who you are looking for doing a keyword search via the person's name will hopefully result in a book or two. The one detail is that a biography needs to have been written. If you are unable to locate your person, contact me, a librarian via chat. There is a chat station on the 4th floor of the library or use your computer going to the library website.
Bibliographies are lists of books, articles, or other materials such as films and recordings. They can be entire books, be within books, or be at the end of journal articles. These are often overlooked resources for related sources; some are even annotated, with short descriptions of each entry. A well-organized, carefully selected and annotated bibliography can lead you to the best and most relevant sources on your topic.
