Annotation in a Citation


Commentary, summary, review, or similar non-bibliographic information concerning the cited work in a bibliographic reference <citation> or <nlm-citation>.


While most citations simply provide the bibliographic information for a cited reference, a few describe the work, categorize the work, comment upon the nature or quality of the work, or summarize its findings. This <annotation> element is intended to hold such commentary.

Display Note: All of the other reference elements are inline elements. In contrast, an <annotation> is typically presented as a block element, with space before and after it.
