There has been a considerable investment of time, money and effort in recent years in the creation of bibliographic records of books. The results are clearly visible. We now have AACR2, MARC records and a whole range of library networks-whether OCLC, RLIN et al in the States, or BLCMP, SWALCAP et al in Britain. We have a new edition of the Dewey Classification Scheme and a new edition of the Bliss Classification scheme. Yet despite all this effort, the databases created, whether an individual library's catalogue or the full set of MARC records on BLAISE, are of strictly limited value.
