example, author, title, publisher, place and year of publication for a
book; author, article title and periodical title, date, volume and page
numbers for a periodical) about an information source. Complete and
properly formatted citations are used to identify and locate an
information source.
You will find that citation
styles vary by academic discipline. The following are citation styles
