<issue>
Issue Number
Issue number of a journal, or in rare instances, a book.
Remarks
Issue Metadata:. Some journal tag sets identify three types of article metadata: that concerning the specific article, that concerning the journal, and that concerning the issue of the journal that contains the article. In this Tag Set, the metadata for the issue and the article has been placed together inside the <article-meta>. In the article metadata, the <issue> is the issue number of the issue in which the article appears.
In Citations: The <issue> element is also used in bibliographic references (<element-citation> and <mixed-citation>) where it indicates the issue in which the cited material was published.
In Joint Issues. If an article was published in a joint issue “Iss. 2-3”, both issue numbers should be placed into a single <issue> element: <issue>1-2</issue>.
