Issue number of a journal, or in rare instances, a book.
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>.
Multiple Issue Numbers: The element issue number (<issue>) is allowed to repeat, to handle the rare circumstance in which a publisher has both an issue number within a volume and an issue sequence number (not volume related) within the run of the publication. In such cases, the attribute @content-type should be used to differentiate the two types of issues.
In this example from an 1897 journal of the Boston Society of Medical Sciences, the “Vol.” was given as “II”, the “No.” as “1”, and the “Whole No.” as “17”. (See Cover: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2121746 and Article: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2121742/.) The article metadata was recorded as follows:

In this example, from the Journal of Medical Research in 1902, the Vol. was given as “VIII”, the “No.” as “2”, and the “Whole No.” as “70”. (See Cover: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2105871/ and Article: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2105865/.) The article metadata was recorded as follows:
