These books are in the reference section of the library (next to the glassed in room with the magazines).
Try these:
Use Destiny (the library's online catalog) to find individual books on your topic (use subject or keyword). Write down the call number from Destiny. Why is this important, you ask? The library has over 20,000 volumes so in order to find the book on the shelves, you'll need the call number!
If you're searching on the web, BEWARE OF WIKIPEDIA. Instead use Webpath Express....someone has already googled for you and chosen the most qualified and helpful sites!
