"An extensive collection of trade catalogs dating from the 19th and 20th centuries. The illustrations generally appear with greater clarity than does the text. Many catalogs pre-date the Civil War although post-war industrialization and production steadily expanded the use of the illustrated trade catalog as a means of advertising for the building supplies industry. Architects, builders and homeowners could consult the catalogs for products that would increase their comfort and convenience as well as enhance the aesthetics of their homes. The collection would well serve the historian and the restorer"--The Library of Congress Guide to the Microform Collections in the Humanities and Social Sciences Division, online version.
