The CD-ROM version of the printed edition of the British Library Catalogue of Printed Books is examined. The utility of the CD-ROM version is discussed in relation to the author's research into 19th century books with photographically produced illustrations. The functions provided by the disc are evaluated, illustrating the great value for bibliographic research of the kinds of access to the British Library's earlier descriptive cataloguing that this digital version allows. The structuring of data and construction of an appropriate relational database are discussed.
