Other indexing services, such as PsycINFO , will only include articles from scholarly journals in specialized fields. Indexes often overlap their coverage. Some periodicals may be indexed in several different sources, but no one index is comprehensive enough to be the only source you need to consult in your research. Format Indexes take many forms. They may be computer databases or paper products.
Some publishers offer the same indexing information in several formats.
The database is also available in some libraries on a CD-ROM, but Ithaca College Library does not subscribe to the service in that format. The important thing to remember is that the same database in different formats include that same basic set of bibliographic records. These summaries are called abstracts . A growing number of online databases also offer the full text of articles. Full text, generally, means only the words of the article.
