Critical: Things Claude Won't Know Without This Skill

LibraryCloud field-based search uses query parameters, NOT Solr syntax

The Item API uses field names as query parameters — not q=field:value Solr syntax.

CORRECT:   https://api.lib.harvard.edu/v2/items.json?title=hamlet&name=shakespeare
WRONG:     https://api.lib.harvard.edu/v2/items?q=title:hamlet

The q= parameter is for keyword search across all fields. Field-specific search uses dedicated parameters like title=, name=, subject=, identifier=, etc.

JSON requires .json in the URL path
