Books are cited in the same way whether they are online or as a hard copy. The author's name is given in full. Book titles should be given in italics and the publisher and date of the publication should be included. The edition should be included (not 1st edition) in the form of '2nd edn' or 'rev edn' for revised edition.
To use a footnote, put a superscript number into your text and then the footnote at the bottom of the page.
