Material Type ISSBD isn't searchable

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

Problem Symptoms:
Searching in the GUI client for material type ISSBD produces no hits. All other materials types *do* produce results; there lots of items with z30_material ISSBD:

Bound Periodical Chemistry Library 22,625
Bound Periodical South Branch Library 416
Etc.

Note: The index being used is the WMT word index, built via the following xxx01 tab11_word entry:

PST## o 03 WMT

That is, subfield "o" from the (virtual) PST field is being used to build it.

Cause:
The PST programs, used to produce the Location display, intentionally exclude individual bound issues -- to avoid a 1000-line display. See Additional information, below.

As described in KB 5534 ("Do bound issues have to change to material type ISSBD?"), "ISSBD" is the z30_material value for the individual bound issues.

The bound volume as a whole has a z30_material value of "ISSUE".

Perhaps there's confusion due to the description of ISSBD as "Bound Periodical".

Resolution:
* If there's confusion due to the description of "ISSBD" as "Bound Periodical", change the description in ./xxx50/tab/tab25.eng to "Bound Issue".

* If a separate index entry for each bound issue is really desired, rather than using the PST $$o, use the expand_doc_bib_z30 routine (to expand the z30_material into the bib record) under the tab_expand WORD label. The expansion of z30 fields into the bib record is described in KB 4116 ("What is expand_doc_bib_z30? What fields can be included in it?")
