The classification scheme used by the library was developed at Union Theological Seminary in New York and is designed specifically for theological book collections. Its notation (symbols) makes use of the 26 letters of the alphabet plus numerals. Some fifteen theological seminary libraries make use of these schedules. A broad table of the contents of this scheme, together with identification of collections by stack decks, will be found below.
