The Calendar (42 page)
To recount Britain’s reform of the calendar I used a number of primary sources, including British state papers from the reign of Queen Elizabeth I, and for the 1750s; and several newspapers and pamphlets from England and the American colonies from 1751-1753
The Gentleman’s Magazine
also provides detailed and entertaining accounts of the reform effort in the 1580s and in 1752. See the issues from March 1751; April 1751; and September 1752. Also see an informative little booklet by H. Dagnall, ‘Give Us Back Our Eleven Days: An Account of the Change from the Old Style to the New Style Calendar in Great Britain in 1752,’ (published by the author, Queensbury, UK, 1991).
For profiles of major characters I read each subject’s original works, plus biographies, articles and biographic citations from encyclopedias and biographical dictionaries. For Roger Bacon the secondary sources included Stewart C. Easton,
Roger Bacon and His Search for Universal Science
(Russel and Russel, 1971); Winthrop F. Woodruff,
Roger Bacon, A Biography
(James Clark & Co., 1938); and Lynn Thorndike, ‘The True Roger Bacon’,
The American Historical Review,
