The Advertising and Promotional Collection contains materials for a wide variety of businesses and organizations in Lancaster County, including manufacturers, department and clothing stores, entertainment venues, grocery stores, restaurants, service providers, and social clubs. Of special interest is the use of both English and German in a brochure from the Great Atlantic and Pacific Tea Co., as well as in the soap-making directions from the Pennsylvania Salt Co. There are also a 1921 program from Lancaster's Colonial Theatre and boxing programs that list Lancaster native, Leo Houck.
The Temperance Collection includes convention programs of the Lancaster County Woman's Christian Temperance Union (W.C.T.U.); a history of the group from 1884-1959; Pennsylvania State W.C.T.U. function programs; and a minute book from the Bart Chapter. Included are handwritten notes on some of the conventions, pro-temperance booklets and newspapers (Moral Reformer and American Reformer), and miscellaneous addresses and articles. Of special interest is a booklet "Operation Interview" in which 36 prominent Lancastrians comment on the question, "Is social drinking necessary for success?", and a newspaper article reminiscing on the temperance movement in Columbia, Pennsylvania.
