A short form of the title of the journal in which the article is published
Many publishers and archives keep an authority file of approved journal title abbreviations. The abbrev-type attribute may be used to hold the name of the authority (if known) that defined this particular abbreviation. For example, “medline” for the medline abbreviation, “publisher” for an abbreviation defined by a publisher such as Elsevier or Blackwell, etc.
More than one abbreviated title may be provided for any given article, possibly using different authorities to determine the abbreviations.
