    13-digit ISBNs -- indexing/retrieval


    • Product: Aleph
    • Product Version: 20, 21, 22, 23
    • Relevant for Installation Type: Dedicated-Direct, Direct, Local, Total Care


    What are Ex Libris' plans for the implementation of the expansion of the ISBN to 13 characters, which may happen as soon as January 2005.


    ALEPH supports a 13-digit ISBN, which is already used in the book industry. (version 16 and up). 

    The 13-digit ISBN always begins with "978", followed by the core 9-digit number and a recalculated check digit. Here's an example:

    Old 10-digit ISBN: 091661736X
    New 13-digit ISBN: 9780916617363

    The 13-digit ISBN is supported in the following manners:

    1) Both 10-digit ISBNs and 13-digit ISBNs are considered valid.

    2) The ISBN validity check routine is capable of validating both types.
    This is relevant when cataloging a record, and when creating or updating
    an Order record (Z68), which contains an ISBN field (Z68-ISBN).

    3) To enable record retrieval by using either type, use the new expand
    procedure "expand_doc_isbn_13" in the "INDEX" section of tab_expand,
    and rebuild the Direct Index (p_manage_05). The new expand procedure
    adds a field with a 13-digit ISBN if the record contains a 10-digit
    ISBN, and vice versa.

    4) The batch process p_acq_24 (General ADM and Orders Creation) has been

    updated such that extracting the ISBN prefix from the BIB record, in
    order to find a matching vendor (Z70), takes into account 13-digit ISBNs.

    5) Note that no changes have been made to the Order Index mechanism in the
    Acquisitions module, with respect to order retrieval by ISBN (Z68-ISBN).
    That is, it's the operator's responsibility to enter the correct number.
    If the operator enters a 10-digit ISBN and finds nothing, they should add
    "978" and search again, and vice versa.
