(a) a full citation, based on the NISO standard for bibliographic citations (National Information Standards Organization 2004?).

(b) a structured informative abstract (when possible); otherwise a structured descriptive or indicative abstract, composed according to the NISO standard for abstracts (National Information Standards Organization 1997b).

Informative abstracts include the purpose, methodology, results, and especially the conclusions of investigations, rather than just describing the investigation. Some documents have no results or conclusions. Examples may include review articles, general discussions, letters, narratives, biographies and bibliographies. For these types of documents, descriptive or indicative abstracts should be included.

The structured format provides for headings for various aspects of the message, such as “Background,” “Aims,” “Method,” “Results,” “Conclusions,” and “Comments.” Abstracts for messages without results can have similar headings. A literature review, for example, could have headings for “Sources” and “Selection criteria.”

(c) A list of index descriptors assigned by human indexers. This applies only to “important” documents, because only important documents receive human indexing.
