WorldCat is a library catalog that lists over 1.5 billionbooks, media and other materials from over 70,000 libraries worldwide.
Many of these items you can have sent to you at Roanoke College for free via Interlibrary Loan.
Search Google Books to find relevant materials on the topic you are researching. Many of the books will only give a "limited preview." Use the Fiintel Library catalog or WorldCat to locate the full copy of the books you are interested in.
