Two examples of mail order catalog directories are Grey House Publishing's The Directory of Mail Order Catalogs and The National Directory of Catalogs from Oxbridge Communications. Grey House Publishing offers its directory of catalogs in an online version as well as the hardbound book.
The directories contain the basic information for each catalog, such as business name, address, phone number and email. They also contain information on the physical features of each catalog, such as size and number of pages.
Grey House Publishing released the 30th version of its directory for 2016, and it included over 5,900 catalogs for consumers and over 2,700 catalogs for businesses.
Oxbridge's directory contains over 12,000 catalogs for consumers and businesses in both the United States and Canada.
