The business and financial correspondence (1967-1990) includes contracts, royalty statements, and check stubs for royalty payments, as well as incoming letters from agents and editors. Although Merrick came from a wealthy family, he seems to have lived to a large extent on royalties, as his correspondence demonstrates. There is an interesting turn in the correspondence when one of his agents Bernard Geis goes bankrupt and Merrick has to sue for back payment of royalties. There are some letters by Merrick, attached to the replies they received, because they are mostly undated. The last dated folder in the series (1989-1990) contains correspondence relating to Merrick's estate.
