Issue Part

The number, name, or other identifier of a sub-part of an issue of a journal, that is displayed or printed with the issue


This is not the machine-readable internal identifier such as a DOI or SICI; that is tagged with the related element <issue-id>. Nor is it the name or number of an entire issue; that is tagged with <issue>.

Some journals seldom or never use sub-issues, and therefore seldom or never use this element. Journals might, however, use it for a large journal issue whose print edition is bound in more than one separate part; those parts might well be numbered or named distinctly despite being parts of the same issue. Distinct numbers or names for each bound portion would then be tagged with this element, while the common identifier of the entire issue would be tagged with <issue>.
