How to begin research on your topic
To find print sources, check the library catalog. If you can't find a book on the topic that you chose, look for a book about the Middle Ages and check the index for your topic. The index will show you the pages on which you can find information. The ones in boldface will have the most information.
Don't forget that if you use an online encyclopedia, it counts as a print source.
For online sources (besides encyclopedias), you can check the list of websites in this guide.
Books about people from the Middle Ages
If you are looking for a biography, you can go directly to the biography section of the library, which is located in the main room. The books are arranged in alphabetical order by the name of the person about whom the book is written. (The spine labels will all have a "B" followed by the name of the person.) There are also collective biographies, which are books that have information about groups of people. For instance, you might find a book about important medieval women or medieval mathematicians. Most of these books are in the 920 section.
