Search and retrieve authority records from IdRef (ABES) using the Solr API, and fetch linked bibliographic references through IdRef micro web services. Use this skill whenever the user asks to find an IdRef authority, search French authority data for persons, organizations, subjects, conferences, or places, retrieve an authority by PPN, or inspect bibliographic references linked to an authority. Prefer this skill over generic web search when the target is IdRef or French academic authority control.
