Deciding where to go to get the information you need is almost as important as finding the information itself. In this module, we'll take a look at three commonly used resources available through the library that will help you find the information you're looking for: the library catalog, periodical indexes, and search engines. At the end of this module you'll be able to answer the following questions:

• What is a library catalog? a periodical index? a search engine?
• What will I find when using each of the resources? How are they different from one another?
• When do I use a library catalog? a periodical index? a search engine?
