Indexes are most often limited to periodical literature but may also include content analysis of conference papers, technical reports, theses, etc. Frequently abstracts are included to summarize the content. Indexes are available in both print or electronic format. Back to Top of Page 2. Determine your information need before selecting the appropriate index.
Many electronic indexes have a searchable field relating to document type.
Look at a database's search fields to see if there is a document type for review article or general review. For current events or a popular treatment of your topic use an index that gives access to magazines or newspaper articles. Use Computer Select or Nexis for the full-text of articles in popular magazines or newspapers. For opinions or editorials use indexes that cover magazines like Science or newspapers like the New York Times. For research to support your ideas use indexes to scholarly journal articles or books.
