You can also use the keyword search to find articles about a particular case. We now also have a web version of the Index to Legal Periodicals available from the Library's home page. This index covers law review articles and books from 1981-date. In addition, ILP does not cover legal newspapers, but does index some books. You may miss a great deal of relevant material if you confine your searching to the full text databases.
Digests provide a subject approach to case law.
The subjects used in the Descriptive Word Index are not particularly helpful in this instance, however. A better approach is to review the headnotes in the cases listed in your Transcript of Record and look for additional cases referenced under those topics and key numbers in the Digests. Check the index for additional annotations. You have to be very careful, however, when you are looking for cases relating to search and seizure and freedom of speech. There are so many cases dealing with these topics that you must always add additional, unusual terms in order to avoid retrieving long lists of irrelevant citations.
