Bliss bibliographic classification
The Bliss bibliographic classification is a library classification system. It was devised by Henry E. Bliss, who was in charge of the library at the College of the City of New York, now known as The City College of the City University of New York. This system, though devised in the United States, was more commonly adapted by British libraries than by American ones.A second edition of the system has been developed in the United Kingdom from 1977. Several volumes have been published.
