[Bug 42102] New: Z39.50 ISBN sometimes fails when right truncation provided
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=42102 Bug ID: 42102 Summary: Z39.50 ISBN sometimes fails when right truncation provided Initiative type: --- Sponsorship --- status: Product: Koha Version: Main Hardware: All OS: All Status: NEW Severity: minor Priority: P5 - low Component: Z39.50 / SRU / OpenSearch Servers Assignee: koha-bugs@lists.koha-community.org Reporter: dcook@prosentient.com.au QA Contact: testopia@bugs.koha-community.org CC: m.de.rooy@rijksmuseum.nl I've noticed that the Z39.50 search for ISBN no longer works for the Library of Congress. It appears that their support for the @attr 5=1 right truncation has changed. If you provide the full ISBN, it will fail. If you provide a partial, it will succeed. The way to work around this is to try both with and without truncation. (Note that places like the National Library of Medicine in the USA will let you provide @attr 5=1 but it doesn't actually perform the right truncation on your ISBN search.) -- You are receiving this mail because: You are the assignee for the bug.

Occasionally getting this error after the patch:
- Present request out of range (ref. 13) for LIBRARY OF CONGRESS result 1
Technically, you'd get that error before the patch too on a successful search. That's an outstanding issue I've found with the Library of Congress Z39.50 MetaProxy implementation. I'm waiting to hear back from the Library of Congress networking team. At the moment, I suspect that there's 1+ bad nodes behind their proxy which cause intermittent failures. Very annoying... -- You are receiving this mail because: You are watching all bug changes.

Yeah, the LOC Z39.50 server is awful.
Do we want this for all searches?
No, just ones with right truncation. At a glance, ISSN would need it as well. Possibly some others if they use @attr 5=1 as well -- You are receiving this mail because: You are watching all bug changes.
