Bowers (1949) refers to enumerative bibliography as a procedure that identifies books in “specific collections or libraries,” in a specific discipline, by an author, printer, or period of production (3). He refers to descriptive bibliography as the systematic description of a book as a material or physical artefact. Analytical bibliography, the cornerstone of descriptive bibliography, investigates the printing and all physical features of a book that yield evidence establishing a book's history and transmission (Feather 10). It is the preliminary phase of bibliographic description and provides the vocabulary, principles and techniques of analysis that descriptive bibliographers apply and on which they base their descriptive practice.
