British National Bibliography vs Ganjoor

The British National Bibliography is the British Library's record of everything published in the UK and Ireland since 1950, now published as BIBFRAME/RDA linked open data through the multi-national "Share Family" platform. Its original bnb.data.bl.uk endpoint has been offline since the Library's October 2023 cyber-attack destroyed its digital infrastructure; the catalog has since resurfaced on a beta institutional search portal, per the Library's own service-status and metadata-services pages.

REST API behind the Ganjoor open-source classical Persian poetry archive, covering hundreds of poets (Hafez, Rumi, Ferdowsi, and more) with full poem text, biographical metadata, manuscript images, and audio recitations. Every read endpoint (poets, poem categories, verses) is fully keyless; only the write endpoints used by the project's own contributor tools require an OAuth2 bearer token.
