You can start your search using the Library's Articles & Books search. From there, move on to the specific databases. If you are not getting good results, remember that adjusting your search terms can make a big difference. It helps to make a written list of possible terms and add to it once you have begun your search and start to see what terms are commonly used to describe your topic.
Another way is by searching the catalog-of-catalogs called WorldCat. When you search WorldCat, the results will be in the order of how many libraries in the system own a copy. If you're interested in getting a book sent here for you, click on the title to find out more about it, and then click on the link for ILL or interlibrary loan (there will be a red icon). You will be sent to the login screen for our ILL system.
