Editing Bliss bibliographic classification (section)

==Adoption and change to BC2==
In 1967 the Bliss Classification Association was formed. Its first publication was the Abridged Bliss Classification (ABC), intended for school libraries. In 1977 it began to publish and maintain a revised version of Bliss's system, the Bliss Bibliographic Classification (Second Edition) or BC2. This retains only the broad outlines of Bliss's scheme, replacing most of the detailed notation with a new scheme based on the principles of [[faceted classification]]. 15 of approximately 28 volumes of schedules have so far been published. A revision of this nature has been considered by some to be a completely new system.<ref name=":3" />

The City College library in New York continued to use Bliss's system until 1967, when it switched to the [[Library of Congress]] system. It had become too expensive to train new staff members to use BC, and too expensive to maintain in general. Much of the Bliss stacks remain, however, as no-one has re-cataloged the books.

The case was different, however, in Britain. BC proved more popular there and also spread to other English-speaking countries. Part of the reason for its success was that libraries in teachers’ colleges liked the way Bliss had organized the subject areas on teaching and education. By the mid-1950s the system was being used in at least sixty British libraries and in a hundred by the 1970s. The Bliss Classification system has been found to be successful in academic, specialty, government, and law libraries. It has also found success in libraries outside of the United States of America, as many of these libraries do not have a history of using either the Dewey Decimal, or the Library of Congress classification system.<ref name=":2" /><ref name=":0">{{Cite book|title=World Encyclopedia of Library and Information Services|last=Wedgeworth|first=Robert|publisher=American Library Association|year=1993|isbn=9780838906095|pages=[https://archive.org/details/worldencyclopedi0000unse/page/132 132–133]|url-access=registration|url=https://archive.org/details/worldencyclopedi0000unse/page/132}}</ref>
