In the sciences especially, it has become customary to cite data from a database by listing, at a minimum, the name of the database, a descriptive phrase or record locator (such as a data marker or accession number) indicating the part of the database being cited or explaining the nature of the reference, an access date, and a URL. In bibliographies, list under the name of the database. See also 14.6–18.
