The series comprises letters written by many Oxford academics discussing a range of college and university business, including the conduct and outcome of examinations, the performance of individual students and organising courses. Some of the letters refer to O. M. Edwards's duties, his plans, applications for posts etc. There are several references to his historical researches and prospective publications. Some of the correspondents discuss Edwards's work as MP for Merionethshire in 1899-1900.

Some of the papers include substantial lists of burgesses.

Most of the letters, 1896-1899, are short, giving family and personal news intermingled with reports of political life at London and other news. There are also several references to their research work on Morgan Llwyd. A few of the letters have enclosures from other correspondents.
