Z39.50
Z39.50 is the ANSI/NISO standard for searching and retrieving records from remote databases, maintained by the Library of Congress and used to query library catalogues across institutions. SRU and SRW re-expressed the same model over HTTP and XML.
Also known as ANSI/NISO Z39.50, ISO 23950, SRU.
Providers that carry Z39.50 0
No provider in the catalog carries this standard as a tag yet. That is a statement about the catalog's tagging, not about adoption: a provider that implements Z39.50 and says so in its APIs.json profile appears here on the next build. Add or correct a listing.
Read from the API Evangelist standards directory. Provider links come from the catalog's own identity tags and are rebuilt nightly. If this page is wrong about a standard or a provider, say so.
