A bibliographic [[index]] is a [http://en.wikipedia.org/wiki/Bibliography bibliography], an aid to search the [[literature]] of, for example, an [[academic]] field or discipline (example: [http://en.wikipedia.org/wiki/Philosopher%27s_Index ''Philosopher's Index'']), to works of a specific literary form ([http://en.wikipedia.org/wiki/Biography_Index ''Biography Index'']) or published in a specific format ([http://en.wikipedia.org/wiki/Newspaper_Abstracts ''Newspaper Abstracts'']), or to the [[analyzed]] contents of a serial publication ([http://en.wikipedia.org/wiki/New_York_Times_Index ''New York Times Index'']). Indexes of this kind are issued in print [[periodical]] form (issued in monthly or quarterly paperback supplements, cumulated annually) or online (in which case they are called [http://en.wikipedia.org/wiki/Bibliographic_database bibliographic databases]). Citations are usually listed by [[author]] and subject in separate sections, or in a single [[alphabetical]] sequence under a system of authorized headings collectively known as controlled [[vocabulary]], developed over time by the indexing service[1].

"From many points of view an index is synonymous with a catalogue, the principles of [[analysis]] used being [[identical]], but whereas an index entry merely locates a subject, a catalogue entry includes [[descriptive]] specification of a [[document]] concerned with the subject".
