The Mid Sweden University Library will shortly start organizing books on the shelves according to a new system. Along with many other Swedish libraries we will switch to the Dewey Decimal Classification System (DDC) which is an internationally wide-spread system based on numbers.
The change will take place gradually over a period of time. The Library at Campus Östersund is already shelving books according to the new system. Härnösand is working on this change right now and will start shelving books according to Dewey in september 2011. In Sundsvall it is mostly new acquisitions of books in English that will be marked and sorted by DDC-numbers. These books are initially placed on shelves separate from the other books for easy location.
The system we are leaving uses letters symbolizing different subjects and is called the SAB-system. It is a system specific to Swedish libraries which has been in use since 1921. The National Library of Sweden decided in 2009 to switch to DDC starting 2011 and the main reason for this is to make classification in Swedish libraries more efficient and international. DDC is translated into approximately 30 languages and it is used in more than 135 countries.
