Outline
• Why consider new translation models of Dewey in Scandinavia?– Sweden– Norway
• The mixed translation model – what is it?
• Exploring the mixed model – the results of the pilot studies and a workshop
• New approaches to the mixed model– Sweden– Norway
• Future work

Classification in Sweden – a background
• Most libraries in Sweden use a national Swedish classification scheme, SAB.
• A Swedish switch to Dewey is under way.– Decision by the National Library to switch from the national scheme SAB to
Dewey. – Recommendation by the Swedish Library Association. – Research libraries have decided or are preparing for a decision.– Interest among public libraries.

Why consider new translation models of Dewey in Sweden?
• Need for a Swedish translation of Dewey
• Until now, the only Dewey content available in Swedish is the Dewey Summaries
• The abridged edition is too brief.
• To translate and maintain the full edition means a lot of work.
• Translations of DDC numbers far down in the hierarchy with little or no literary warrant in Sweden would be of limited value.
• Following the Norwegian example, with an abridgment of our own – Could cause problems with interoperability. – Would be time consuming in itself.

Classification and indexing in Norway – a background
• Dewey is used by most libraries in Norway
• Use of different editions of Dewey (DDK 5, DDC 21, DDC 22 and WebDewey)
• Norway has no national subject heading system
• Different local indexes to Dewey in OPACs
www.kb.se
DDK 5
• DDK 5 based on DDC 21• Special customized edition on the level between Abridged and full DDC• Level of abridgment based on literary warrant in Norwegian libraries• Used by:
– Public and school libraries– Biblioteksentralen (The Library Center)– The National Bibliography
• Used for reference and for specific subjects by university and special libraries, but in general they use DDC 22 /WebDewey
• DDK 5 is important for development of Norwegian terminology in local subject headings
www.kb.se
Why consider new translation models of DDC in Norway?
• Use of different versions of Dewey makes reuse of classification numbers in the copy cataloging process difficult
• Use of different versions of Dewey makes it difficult to search by Dewey numbers across catalogs
• One version of Dewey would make it easier to create end user tools (a la MelvilSearch) which could be used across catalogs

Important considerations before switching to a web version
• How can the classification praxis be more standardized among all Norwegian libraries?
• Is it possible to develop one edition of Dewey which could be used by all libraries?
• Is it possible to develop a model which is not as time consuming as translating the whole Dewey or continue the special customized DDK?
www.kb.se
What is the mixed translation model?
• Use Dewey data in the vernacular as framework
• Update the vernacular data to match the current version of the DDC
• Where needed, add English-language classes from full edition to complete hierarchies
• Translate the auxiliary tables (Tables 1-6) in full
• Use standard terminology for instructions in the language of each record (e.g., “Her:” / “Class here”)
• Include logical abridgment instructions to address use by smaller collections
• Provide separate indexes featuring the terminology available in each language

Pilot studies
• Usability as a classifier’s tool
• Navigation between Norwegian and English terminology
• Difference between classifying Norwegian or English literature?
www.kb.se
Advantages
• More index terms
• Index terms in both English and Norwegian
• The whole Dewey from one source
www.kb.se
Disadvantages
• Norwegian content in instruction notes and including notes disappeared
• Not all Norwegian librarians have mastered English well enough to use it as an entry point to Dewey.
• Confusing with mix of languages
www.kb.se
Workshop
• Arranged by the Norwegian committe on classification and indexing (NKKI), the National Library, and Library Education
• What level do we need for a new Norwegian translation?
• Is it possible to create a Norwegian edition which could be used by all libraries?
www.kb.se
New approach to the mixed model - Norway
The workshop gave a recommendation for full translation:
• Norwegian terminology is important.– for cataloguers to understand the instructions in Dewey and classify fast and
correctly. – as a basis for subject headings– as an access point for librarians and end users
• Need for consistency in classification - easier to maintain if all libraries use one Dewey edition
• Those who use a full edition today would not use a mixed edition
• The need for exchange of classification data makes it important with interoperable data
• A full translation needs abridgment instructions on DDK level.
www.kb.se
Future work - Norway
• NKKI will give a recommendation to the National Library on a full translation with abridgment instructions
• If not a full translation: How to use the experiences from the Mixed edition project?
– a datafile containing the full (English-language) Dewey from which we can produce an abridged Norwegian version?
– abridged on DDK-level with extended index?– indexes in both Norwegian and English?
www.kb.se
New approach to the mixed model - Sweden
• For Sweden, the mixed model still seems to be a possible way to reach a Swedish translation in reasonable time and with reasonable resources.
• Differences from the Norwegian circumstances– No translation at all to start from.– University libraries are the main user group.– Svenska ämnesord (Swedish subject headings) is an additional access point
and source of terminology.– SAB does not provide detailed notes, and the scheme is not extensively
indexed. Swedish librarians are used to coping without this kind of information in the classification scheme.
www.kb.se
Level of initial translation to Swedish
• Dewey classes mapped to SAB in the converting table SAB-Dewey.
• Dewey classes found in the abridged edition of DDC.
• All superordinate classes to translated classes.

The abridged DDC will complement the level
363.4 Controversies related to public morals
• No counterpart in SAB.
• Will still be translated, since it is a number from the abridged edition.
www.kb.se
Future work - Additional translation into Swedish
Guided by:
• Literary warrant in LIBRIS, the Swedish union catalog
• Need for Swedish terminology and Swedish examples, based on problems reported by Swedish librarians.
• Work in progress
• Possibly an intermediate step on the way to a full translation?
www.kb.se
Future work -The mixed edition as an end-user tool?
• The mixed edition as an end-user tool has not been studied yet.
• How will the mix of languages work for an end-user, possibly with no knowledge of English?
• Browsing top-down – no big difference from using an abridged edition for browsing.
• Searching could be more of a problem, but the mappings SAO-DDC will help up the situation
• Plans for a pilot study of the mixed edition as an end-user tool using MelvilSearch.

The Swedish Dewey project
Goals:
• Translating Dewey to Swedish using the mixed model
• Mapping Swedish subject headings to Dewey
• Developing tools to search and navigate material with SAB codes and material with Dewey numbers together.
• Training
• Start May 2009
• The Swedish mixed edition will be made available when a reasonable amount of the content is translated into Swedish.
• National Library switches to DDC in 2011 or 2012.
• Libraries can switch to DDC during the project, or wait for the switch of the National Library.
