The collection encompasses aspects of Professor Granger's personal, academic and official life. It contains correspondence with family members and colleagues; papers relating to his career and published works; antiquarian papers; and records of his involvement in developments and activities of University College Nottingham. The latter series includes illustrations of the opening of new buildings in 1928 and of a visit by princes of Hyderabad in 1931, as well as letters about arrangements for Albert Einstein's visit in 1930. Granger's interest in the Nottingham miller and mathematician George Green is reflected in several historical items.
An uncatalogued accrual of several items has been transferred to the Department of Manuscripts since completion of the catalogue.
