Citing "Old Style" Dates


Dates from 1582 on used in name headings are given in terms of the Gregorian calendar.  If a particular reference source uses the Julian calendar (also known as Old Style [o.s.] or Lady Day dating), transcribe the date in the 670 as it appears in the source but correct the date or make the dating style explicit in square brackets.  Use the Gregorian date in the heading.

See: AACR2 22.17A and the article "Old Style-New Style" by W.W. Greg in his Collected Papers, edited by J.C. Maxwell (Oxford : Clarendon Press, 1966).

Example:

010:  : |a nr 00029133
