The collection is roughly divided into the business records of I. and R. Morley (Mrl 1), and papers of the Morley family (Mrl 2).
The business records include financial records, correspondence and legal papers, advertising and price lists, papers relating to property and estates. Materials collected by staff at I. & R. Morley concerned with the firm's own history include papers relating to the research for a book in the late 1940's and scrap books including one about the factory in Ballarat, Victoria, Australia. The business records also include account books from 1799-1859 and articles of partnership and legal agreements 1818-1964.
As a family business there is often no clear distinction between business and personal matters. The family papers, the bulk of which is correspondence, include wills, executory and other legal records dated 1750-1886; receipts and other financial papers c.1710-c.1841; family and business correspondence 1800-1874; and correspondence with family lawyers Wells and Hind, 1834-1895. The papers are largely those of Richard (senior) and Arthur Morley but records of Benjamin, James and William Morley, Elizabeth Widdowson and William Statham are also present. As primarily a business collection, many of the documents concern legal and financial arrangements, and money appears to have been the cause of some dispute between the various family members. There are also legal documents and plans relating to land at Sneinton (including before it was acquired by the Morleys) and elsewhere.
