in Sweden. It primarily classifies books but is also used for other media, such as audio and video recordings. The first edition of the system was released in 1921 and was based on the classification that was used in the accession catalogs of the scientific libraries of that time. The abbreviation 'SAB' is for "Sveriges Allmänna Biblioteksförening" (''Sweden's public library association''). SAB merged with Svenska bibliotekariesamfundet (''Swedish librarians' association'') to form present day

(''Swedish library association''). The SAB system is regularly revised to track developments in new subject areas. The committee for classification systems for Swedish libraries — a part of Svensk Biblioteksförening — promulgates changes, corrections, and usage notes. Larger revisions may cause changes to the whole system and a new version of the classification system is published. The latest, eighth revision was started in 2002 and was put in use in autumn 2006.

) and the public libraries decided at the end of 2008 to recommend a transition to the Dewey Decimal system. The research libraries' major reason for transitioning are simplification: large parts of research literature is already classified in this system. For public libraries the concern is to have the same classification system over the entire country. A considerable savings would be enjoyed by both parties by not having to maintain a distinct national classification system.

Structure

SAB is built in a

'' and Cge for cathechethics. There is in principle no limit to how many subcategories can be formed in this way.

Additional notation

A signum can be made more precise with additional notation. The following additional notations exist: * Geographic division (expressed with a hyphen) : Ab ''Libraries'', Ab-c ''Libraries : Sweden'' or Qaea-j ''Monetary systems : France''. * Chronological division (expressed with a period) : Kc.3 ''Swedish history : Middle ages''. * Language specification (expressed with an equal sign) : Kj=e ''History of France: in English'' * Aspect (expressed with a colon) : F:do ''Language : psychology'' or Pcj:k ''Telephony : history'' * Biography (expressed with 'z' and the name of the subject of the biography) : Dcz Chomsky, Noam ''Logic and language-oriented philosophy : biographies of Noam Chomsky'' * Type of work (expressed with parentheses) : Ke(u) ''English history :

These always begin with .0. For instance, the category Fc (''the Swedish language'') can be subdivided * Fc.00 ''History of the Swedish language'' * Fc.01 ''Swedish grammar'' * Fc.011 ''Swedish phonetics'' * Fc.02 ''Swedish vocabulary'' etc. Additional notation may be combined. Thus, Ab-c:b(p) for ''Libraries : Sweden : research : periodicals''.
