Journal Identifier


Short code or abbreviation used as an identifier for the journal

There may be more than one such identifier; the type of identifier can be named using the journal-id-type attribute, for example, the identifier may be a DOI or a control number assigned for a publisher’s internal processing.


For NLM’s PubMed Central and other NLM-internal processing, this element contains an alternative to, or short form of, the journal title, used to identify the journal domain. In such processing, this element is the equivalent to, and usually used instead of, the <abbrev-journal-title> element. Outside of PubMed Central processing, this use of the <journal-id>element is rare; typically journal DTDs use the <abbrev-journal-title> element to hold the short version of a journal title and the <issn> element to hold a journal identifier, rather than creating a separate identifier for the journal. For journals that have assigned an non-ISSN identifier (typically numeric) for individual journal titles, this <journal-id>element can hold that identifier.

NLM PubMed Central Authoring/Conversion Note: In PMC processing, the short journal title identifiers used in this element come from an authorized list, so that each journal code is unique within the PMC system. The <journal-id> holds the PMC short abbreviation of the journal title, which identifies the journal domain. The content of this element may thus be repeated in the <abbrev-journal-title> element, or the publisher’s abbreviation may be used in the <abbrev-journal-title> element.
