You may be familiar with one kind of index -- the alphabetical listing of topics in the back of a book -- that helps you find where a particular topic is covered in the book.

Librarians also make reference to an additional kind of index.  For decades subject indexes to the content of journals and newspapers usually in a particular field of information were published and provided the primary way to find articles on a particular topic.  For example, Art Index contained article citations from hundreds of journals and magazines in the field of art and included indexes by author, title and subject for each citation.

Most of these formerly print indexes have been replaced by databases that do exactly the same thing -- contain thousands of citations to resources such as books, articles, etc. that can be searched by keyword, author, title and subject.
