<isbn> ISBN

International Standard Book Number, the international code for identifying a particular product form or edition of a publication, typically a monographic publication, but standards documents are frequently assigned ISBNs.

Usage/Remarks

Within an ISBN, spacing, hyphens, and punctuation should be preserved.
ISBNs can be assigned to books, reports, standards documents, conference proceedings, and dissertations. The <isbn> element can be used to record all such numbers inside bibliographic citations (<element-citation> and <mixed-citation>). Within a mixed-style citation, the text “ISBN:”, if present, should be kept as text within the citation but not placed inside the <isbn> element. Within an element-style citation, the text “ISBN:”, if present, should be removed from the citation and also not placed inside the <isbn> element.
