The materials contained in oversize materials are those which were too large for the standard linear foot box. The items include eight subject areas: Land Mortgage Company, Texas Land Mortgage & Development, Louisiana Maps & Land Promotion, J. B. and Elizabeth Watkins, Lawrence Canning Company, Kansas City, Watkins & Gulf Railway, Texas Maps & Industry, and Louisiana Maps & Industry. Included are such varied papers as promotional pamphlets, Lawrence Canning Company labels, printed and handwritten maps, and an agent's rubber stamp. Other materials have been added to various oversize call numbers over the years and are similar in type of document but not necessarily arranged in the same way.
