Edward Granger's papers consist of a diary and a scrapbook. The first portion of his diary (November 29, 1858 – February 20, 1859) was written while Granger was attending Michigan Agricultural College. He discusses classes, work assignments, daily routine, and recreation. The second portion (January 1, 1860 – February 1860) was written while living with his parents in Detroit, Michigan. He describes in great detail his daily routine, reporting on his classes, work assignments, and wintertime recreational activities such as snowball fights, hunting, and sleighing. The last pages of the diary consist of passages copied from his readings and Latin exercises.

In his “Scrapbook,” Granger recorded the hours he spent laboring at various farm jobs at M.A.C. and a few class notes.
