USC Libraries Discovery (Ex Libris Primo VE, Tenant)
USC Libraries' catalog and discovery layer runs on Ex Libris Primo VE as institution view 01USC_INST:01USC at uosc.primo.exlibrisgroup.com. The public Primo configuration REST endpoint /primaws/rest/pub/configuration/vid/01USC_INST:01USC returns 200 JSON naming "Southern California" and linking libraries.usc.edu, which is how this view was disambiguated from 61USC_INST:61USC — that one is the University of South Carolina, a different institution whose Ex Libris code differs only in its numeric prefix. Recorded as a relationship: the host is Ex Libris's, the contract is Primo's and is shared by every Primo customer, and no Ex Libris specification is saved under USC. USC's Alma institution code is not exposed through the generic Alma OAI-PMH gateways — na01 and na02 /view/oai/01USC_INST/request?verb=Identify both answer 200 with "Institution code 01USC_INST is invalid" — so USC publishes no harvestable library metadata feed.
