3. Retrieve two or three records from your search and locate the lists of descriptors. Compare the lists and note the areas of commonality as well as differences. • Write down the exact wording of three descriptors that relate to your intended topic. Choose descriptors that reflect your personal interest in the topic. • Compared to the simple phrase you used when you started, do you think these descriptors are more specific or more general? Why? 4. Now use the descriptors you just located to modify the search. • First, modify the search to select more records. • Then, modify the search to select fewer records. • If you used the connector AND, did it result in more or fewer sources? Why do you think this happened? • If you used the connector OR, did it result in more or fewer sources? Why do you think this happened? 5. If necessary, narrow the search further until you have between 50 and 150 sources, and print out the search results. • Carefully scan the printed list to identify several possible subcategories. • Compare the new categories to your original topic. • Redefine your topic more narrowly, and identify the articles that pertain to your new topic. Prepare a list of the references for these articles.
