    Dewey Classifications

    The Dewey Classification is displayed in Analytics in the Dewey Classifications shared dimension, available in several subject areas. Dewey classification information is derived from the holdings record for the Physical Items subject area, and the bibliographic record in other subject areas.

    From Bibliographic Record:
    From Holding Record:
    • For MARC21
      852$$h When the first indicator is 1

    • For UNIMARC
      852$$h When the first indicator is 1

    There are three levels of the Dewey Classification stored in Alma Analytics. Each level is referred to by a numbered group (Group1, Group2, and Group3).
    The group fields display the names as follows:

    Dewey Classifications Groups

    Dewey Classifications Groups

    Using the hierarchy option in this dimension, the user can drill down from Group1 to Group3. In each level, the user can see measures accumulated to the relevant group.

    For example:

    • 000 Computer science, information & general works

      o    010 Bibliography

      o    000 Computer science, information & systems

      • 005 Computer programming, programs & data

      • 000 Computer science

      • 004 Data processing & computer sciences

    This is presented in Alma Analytics as follows:
