Consists of Houghton Mifflin file copies, supplemented by items removed from Houghton Mifflin business records during processing. Coverage is incomplete: only scattered publications to 1880, fairly comprehensive from 1880-2004. Many items are annotated with date of publication and number of copies printed; some have been annotated (sometimes heavily) by company officials, most notably a series of catalogs (1930-1934) containing information on book club sales and agreements with English publishers. Includes general, seasonal, and subject catalogs, some in serial form, e.g. The Riverside bulletin (1871-1872), Literary bulletin of Houghton, Mifflin and Company (1879-1894), Catalogue of books published by Houghton, Mifflin and Company (1881-1896/97), A Portrait catalogue of books published by Houghton, Mifflin and Company (1897/98-1910), A Complete catalogue of the books of Houghton Mifflin Company (1911-1968), The Piper (1918-1932), Educational progress (1921-1930). Catalogs of books and services (e.g. testing) for the educational market begin ca. 1903 and predominate after ca. 1940. Also includes 2 George A. Leavitt & Co. auction catalogs (28 March 1876, 4 April 1878) for the sale of stereotype plates, remainders, and publication rights. Items in the Bound set series mostly duplicate items in the Unbound and separately bound publications series.
