To locate biographies in the library, use the catalog. Enter the last (family) name or the first and last name of your subject in quotes.
For example if you are searching for Albert Einstein, you could enter either Einstein, or "Albert Einstein" In some cases you will want to always enter the full name, for example, entering King for Martin Luther King will bring back books and articles about Kings and more, so you should enter "Martin Luther King"
When you are at home or on the Rowan campus, use the Rowan catalog search, called Prof Search:

Remember, if you have any questions, don't hesitate to contact your librarian.
