    • Product: Aleph
    • Product Version: 20, 21, 22, 23

    How is Item availability retrieved from Z39_server?


    1. The Z39.50 OPAC format has an "availableNow" variable. "1" means "available / not on loan", "0" means "not available / currently on loan". 
    2. AVA field created by expand_doc_bib_avail expand routine has available/unavailable information based on items and holdings data. Created per Collection. 
      1. Add expand_doc_bib_avail program to routine Z39_SERVER in ./xxx01/tab/tab_expand. 
      2. Add AVA field to ./xxx01/tab/tab04.

    Additional Information


    For an explanation of the expand_doc_bib_avail program, refer to the "Aleph Publishing Mechanism" document (attached). 

    Also, see article: How to display Item information in z39 server. It does not have availability information, but has a good example for tab04 setting for z39.50.
