Classification

SCIS uses the Dewey Decimal Classification (DDC) system to organise library collections for information retrieval purposes. SCIS adopts the current editions of DDC as they become available. The current editions are the 22nd edition of the full classification, DDC22, and the 14th edition of the abridged classification, ADDC14.

Changes from the 21st edition are not major. The areas with significant revisions and additions are 004-006 Computer science, 305-306 Sociology and 610 Medicine. There are also some relocations and expansions to improve 510 Mathematics. Click on DDC 22 for details of the changes.

WebDewey and Abridged WebDewey
DDC22 and ADDC14 are available by subscription on the Internet. WebDewey and Abridged WebDewey provide browser-based access to enhanced versions of the full and abridged Dewey Decimal Classification databases. Schools interested in taking out a subscription will find order details and a link to order forms at

Call numbers

Libraries assign call numbers to each resource in their collection. The call number comprises two elements:
  1. Classification number
  2. Book number

The classification number places the resource into its discipline or field of study. The book number is a device, usually alphabetic, for subarranging resources with the same classification number and for keeping works by the same author together on the shelves. The classification number plus the book number is the call number. It provides a unique identifying code that is used as an "address" on the shelf, and as a tag for library record keeping in circulation and inventory control.

Call numbers in the SCIS database comprise a classification number and up to three alphabetic characters for the book number, usually the first three letters of the first filing word of the main entry, e.g.
All kinds of animals / by Sally Hewitt has the call number   590
HEW

The field of study is a general work about animals, DDC 590, and the author is the main entry so the book number comprises the first three letters of her name, i.e. HEW.

Sometimes the title is the main entry and the book number comprises the first three letters of the title, e.g.
Walking with beasts [website] has the call number   569
WAL

Tales of the catwings / Ursula K. Le Guin has the call number   F
LE

Exceptions

  • biographical works where the book number is the first three letters, or first filing word, of the name of the person, or family, who is the subject of the work
  • commentaries and critical works where the book number is the first three letters, or first filing word, of the author or work being written about
  • abridgements and adaptations of literature and folklore where the book number for the original work is used
  • works where DDC instructs to sub-arrange alphabetically specific classes, e.g. specific cars, computer programs, television programs and films where the book number is the first three letters of the name of the car, program or film
  • English literatures classification numbers
  • Shakespeare book numbers
  • Australian Aboriginal peoples: if the book number would be ABO we use ABL.

Mismatched call numbers on old resources
Sometimes the spine label on an old resource does not match the call number on your SCISWeb record. This can either be due to a change in the classification number and your label relates to the obsolete number or because the old classification number has not yet been updated on SCISWeb, e.g. folklore area. To establish which number is correct, search the database on the same title or subject heading for more recently catalogued records and change the spine label or your SCIS record to match the new number.

NB SCIS record numbers are generated consecutively and the more recent the record the higher the record number. To establish current record numbers, check one of your recently catalogued resources.

Literature numbers

  • A820 and NZ820

    SCIS distinguishes Australian and New Zealand English language literatures by giving them local emphasis and shorter classification numbers. This is achieved by using initial letters to create the classification numbers A820-A828 and NZ820-NZ828, e.g. the Australia poem

    Mr Magee and the biting flea / by Pamela Allen
    has the DDC22 call number

    A821.3
    ALL

    and the ADDC14 call number

    A821
    ALL


    The call number for the New Zealand poem

    Hairy Maclary from Donaldson's dairy / by Lynley Dodd
    has the DDC22 call number

    NZ821.2
    DOD

    and the ADDC14 call number

    NZ821
    DOD


    Period numbers

    Note that the above ADDC14 numbers do not include numbers after the decimal point. This is because only the full edition of Dewey provides a special period table for Australian and New Zealand literature.

    In DDDC22 the century in which the work was written can be added to the base number. New works by authors whose main body of work was written in the 20th century will continue to be classified at the 20th century. Authors who first publish in the 21st century, or whose larger body of work is written in the 21st century will have the number for the 21st century added to the base number for their work. For Pamela Allen's recently composed poem, the period table number 3 for Australian 20th century literature has been added to the base number to give the number A821.3.

    In Lynley Dodd's poem the period number 2 for 20th century New Zealand literature has been added to the base number to give the number NZ821.2.

    Both the above authors' works were largely written in the 20th century.

    The poetry of Australian author Kate Fuderer has only been published since 2000. Her works are classified as 21st century poetry and the period table number 4 for Australian 21st century literature is added to the base number, e.g.

    Claud the cat's bump / by Kate Fuderer
    has the DDC22 call number

    A821.4
    FUD

Myths and mythology - 292.13 versus 398.2

The Dewey manual has recently clarified the classification of these works:

"Use 398.2 for myths or mythology presented in terms of cultural entertainment or, especially, as representative of the early literary expression of a society, even if they are populated by gods and goddesses. … For example, use 398.2 for Greco-Roman myths retold for a juvenile audience… If in doubt, prefer 398.2 ".

291.13 is only used for strictly theoretical works on classical mythology.

This ruling has resulted in some inconsistency on the SCIS database. Many older records have been classed at 292.13, whereas more recent records have been classed at 398.2.

SCIS intends to update older records to 398.2 as work commitments permit. However our priority lies with new items still available for purchase.

Shakespeare

Dewey provides a specific classification number for works about and by William Shakespeare. Specific book numbers are also provided for users of the full version of Dewey, DDC22.

  • Primary schools - ADDC14 number 822.3
    For works by Shakespeare, the book number will be SHA.
    For retellings and for works about Shakespeare, the book number will be the first three letters of the author's name, or the title if there is no author given. (Note, there is no need to use SHA as the book number, since all works classed at 822.3 will relate to Shakespeare).

  • Secondary schools - DDC22 number 822.33
    Dewey provides specific book numbers for individual works and criticism, as well as for collected works, adaptations, general criticisms, biographies, etc.

    The book number for general works consists of a single letter, e.g. B for biographies, H for adaptations.

    The book number for single works consists of a letter and a number. Odd numbers are used for the works themselves and even numbers for criticisms, etc, e.g. Hamlet - the play : S7 ; Hamlet - a criticism : S8.

Classifying videorecordings

The WA Cataloguing Agency is seeking comments from WA schools about the classification of videorecordings on SCISWeb.
We are trying to establish whether schools are happy with the current system where videos are shelved according to the content of the program or whether they would prefer to keep all videos together on the shelf regardless of the content.

The table below provides a sample of videorecordings and their current classification together with other options. One option is to keep all videorecordings together regardless of the content, other options are alternative Dewey numbers for particular types of videorecordings. A key below the table shows each Dewey number listed and what it represents.



Title Current classificiation Option 1 Option 2
William Shakespeare's Romeo & Juliet / directed by Baz Luhrmann 822.33

  4. 598 - Birds
  5. 994.104092 - History of Western Australia
  6. 791.43028092 - Actors in motion pictures
  7. 914.404 - Geography and travel in France
  8. 782.1 - Operas
  9. 782.14 - Musicals
Points to consider
  • Should all resources on same topic regardless of physical format be kept together? e.g. any resources on birds including videorecordings, charts and books on the shelves together at 598.
  • Classify all videorecordings at 791.43. Do you consider that all videos are public performances, as this is the area in Dewey where the number appears. How would someone find a specific video on a topic such as birds if it was located with all other videos at the same number?
  • Classify videos according to content. Should variations of a type of content be a consideration? e.g. some musicals are all songs, some have sections of dialogue interspersed with song, should they all be treated the same?
  • Shelving different forms of resources separately. It may save space by tailoring shelving to the size of the videos and save people looking through other resources when they only want videos. However, you will need to go to separate areas in the library to find all of the materials on a given topic and still need a system of organisation to enable easy access.

Classifying websites

Websites are not physical items that we need to shelve so why give them a call number?

There are a number of reasons for classifying websites:

  1. Classification numbers can be used as an accurate and easily identifiable device to assess the balance of a library's collection on which can be based collection development policies and activities. Websites are a library resource as much as are 'traditional' library resources and, by classifying them, they can be included in subject and resource type collection development strategies. This is important today with an emphasis on ICT in curriculum.
  2. Some websites are part of a mixed media resource that includes print materials and non-print materials such as audio cassettes, CD-ROMs, etc. Some of these websites provide such additional material as web quests, exercises and educational games, bibliographies of useful subject related web sites, printable worksheets and fact sheets, images, etc. An example of multimedia resources is:
      Minerals downunder [kit] SCIS 976948 and the factsheets website http://www.agso.gov.au/education/factsheets/index.jsp SCIS 1042275
  3. Many websites contain downloadable pdf files that librarians may want to include on the shelves in their collection. These can be put to the same classification number as the website.
  4. In some library systems the MARC 082 field (classification/call number) may be a mandatory field and must be filled in to create a record.
  5. Classification schemes are used in some network environments to aid navigation and retrieval, specifically with regard to the Internet. Classification schemes give hierarchical access to indexed Internet resources. Browsing structures based on subject classification compliment search engines that give access to selected Internet resources. In classifying websites, the SCIS database is positioned for future developments in Internet resource description and retrieval systems based on the Dewy Decimal Classification scheme.
