The Eli P. Zebooker Collection is an exemplary group of 18th and 19th century materials with a particularly strong focus on the geography and built environment of Greater Philadelphia. Donated to the Athenaeum in October 2010, it consists of 127 items including 62 books (see Athena on-line catalog), 33 maps, 30 prints, 1 newspaper and 1 set of commemorative postage stamps. It includes materials that range in date from 1750 through 1979, although the bulk of the collection predates 1900.
