Published between 1862 and 1932, and reissued here in multiple parts, this monumental calendar of documents remains an essential starting point for the serious study of Tudor history. An experienced editor of historical texts, John Sherren Brewer (1809–79) had no prior training in the history of the period, yet he brought to the project the necessary industriousness and an impeccable command of Latin. Four volumes appeared before his death, whereupon James Gairdner (1828–1912), his former assistant, took up the editorial reins. Continuing Brewer's method of ordering chronologically all available documents from 1509 to 1547, and reproducing some passages while paraphrasing or omitting others, Gairdner brought the project to its conclusion, aided himself by R. H. Brodie (1859–1943) in preparing the later volumes. Part 2 of Volume 3 (1867) has been split into two for this reissue: this first half covers the period from July 1521 to 21 October 1522.
