Template documentationProduces a cited reference to John O'Donovan's edition and translation of the Annals of the Four Masters, available in print and electronically, as PDF-file and in part in HTML code.
Since the dates given in the Annals of the Four Masters do not necessarily correspond with Anno Domini dating in this period, they are often cited as "s.a. 563" (from the Latin sub anno, 'under the year') rather than "AD 563". An alternative method uses the year and the section in which the cited entry appears, so that the second entry under the year 563 would be cited as "563.2".
For example:
{{Cite AFM|postscript=s.a. 563, 621, 789.}}produces:
