We will spend some time looking at keyword and subject heading searches because I think they are worth some time to consider. Keyword searching For keyword searching, you may type in words that describe your topic. There are a variety of ways to do this. If you just type in several words, the catalog will search for records that contain each of the words you have typed. The more words you add in this fashion, fewer and fewer items will be found.
Subject heading searching Every item in the catalog is given a subject heading to describe it.
Remember, these are given by librarians and they need to have a relationship with other headings in the catalog. The Catalog requires librarians to be very specific and to offer definitions and explanations of terms. By first doing a keyword search and then clicking on the subject heading of a record you like, you will be able to find additional research material. The most important thing to remember that there are different indexes for different subject areas. Indexes have a long history in libraries.
