Follow the bibliographic style prescribed, e.g., APA, MLA, Chicago or others.
Annotation: a brief description or explanation of the material, intended as a guide for the reader. It may be descriptive: indicating the major points of the work or evaluative: giving the annotator's opinion of the work.
