Training uses the online catalog as a jumping off point, to provide skills that can then be taken to periodical databases or the Web. There are two general rules of searching. First, help is available. Second, when in doubt, read the screen. The second step is refining.
Subjects are usually too big or too small.
If a subject is too big, the patron must limit to narrow the search. The third step is showing the results of the search. It may be possible to sort the results so the list is in a different order. The fourth step is to write. Many patrons are disappointed when the full content is not completely available on the screen.
