Internet searches. Researchers using a search tool such as Google usually begin with a keyword search. Because the Internet contains vastly more material than the largest library catalog or database, Internet searching requires care in the choice of keywords. For example, if you need information on legal issues regarding the Internet and enter Internet and law as keywords in your Google search, you will get over three million hits. You may find what you need on the first page of hits, but if not, you will need to choose new keywords that lead to more specific sources.
