The Goldsmiths' Library contains the major colection of historical economic literature in the English-speaking world. It includes periodicals, pamphlets, manuscripts and autograph letters-as well as printed books-from the fifteenth century to the present day. The Catalogue, in four volumes, constitutes an essential bibliographical tool and is the key work of reference for early economic literature. It includes all works of economic literature in the library, covering the period from 1470 to 1850. The entries are arranged chronologically under the year of publication, and from 1601 onwards this year-by-yera arrangment is supplemented by 14 subject divisions.
