    Z39 Server Bad Data Display

    • Article Type: General
    • Product: Aleph
    • Product Version: 20

    Problem Symptoms:
    Records display wrongly in z39.50 server using the Yaz client. Subfield codes and indicators are misplaced, many fields are empty:

    321 $ $ aSemestriel, $
    362 $ $
    500 $ $ aTitre de l'?cran-titre (visionn? le 18 mars 2004). $
    506 $ $
    538 $ $
    650 $ 6 $ a?ducation $
    650 $ 6 $
    659 $ $


    The normal display is:

    655 6 $a P?riodiques

    Cause:
    Bad data: records had "00" in LDR positions 10-11. These positions define the indicators and subfields offset.
    The correct values for LDR/10-11 is "22".

    Resolution:
    LDR positions 10 and 11 were invalid in the affected records. LDR positions 10 and 11 must be set to "22".
