Every record says where it came from.
Libra Esoterica is a discovery snapshot, not a library of record. Each book here was assembled from one or more of the catalogs below, and every field — title, dates, subjects, description, cover — is attributed to the source that supplied it. When sources disagree, we keep both readings and note it.
Access labels (“public”, “restricted”) are what the source reported at harvest time. They are not legal advice. Read the rights notes.

Open Library
Work and representative-edition metadata, ISBN/LCCN/OCLC identifiers, subjects, covers, and access indicators.
General search results are capped per subject query. A separate oldest-first historical route requires a source-reported first-publication year no later than 1899 and covers every controlled taxonomy query, with a higher result ceiling for selected high-yield historical subjects. Open Library reports that catalog contributions are intended for open reuse, but individual fields can originate from many contributors.

Bavarian State Library Digital Collections
Pre-1900 digitized rare books and manuscripts with stable BSB and URN:NBN identifiers, creator GND authorities, OCLC/ISBN/DOI metadata, publication details, shelfmarks, provenance, extent, scan counts, item-level rights, public IIIF manifests, and scalable page images.
Discovery uses the provider's public simple-metadata search API, a pre-1900 date facet, book-media filtering, oldest-first pagination, and controlled German, Latin, French, and English subject terms. Unique BSB records are enriched through the public item-metadata endpoint. IIIF manifests are represented as public page-image access, not PDFs; the provider's PDF workflow is retained as a download landing page because it does not expose a stable direct-file URL in search metadata.

Internet Archive
Date-bounded discovery of institutional pre-1900 texts and manuscripts, plus public scan landing pages, bibliographic identifiers, descriptions, thumbnail files, file-level PDF URLs, and item license metadata.
Historical discovery uses exact subject phrases, an edition-date ceiling of 1899, and oldest-first ordering. One route selects institutional/library collections; a complementary global route requires search metadata to advertise a PDF format and excludes restricted items. Only exact PDFs and thumbnails exposed by an unrestricted item metadata file listing are promoted to direct-file or cover fields. Public access does not by itself establish public-domain status in every jurisdiction.

The Online Books Page
University of Pennsylvania-hosted curated online-book records with stable IDs, Library of Congress subjects and call numbers, contributor credits, bibliographic notes, descriptions, and exact links to freely readable copies at source repositories.
The adapter scans the source's CC0 curated raw catalog, excludes serial archives, and retains records only when a Library of Congress subject matches the controlled taxonomy. The Online Books Page reviews the linked copies for legal online availability, but target-site copyright and reuse terms can vary by jurisdiction. Its LCCN field contains call numbers and is therefore preserved as a note rather than misrepresented as a control number.

Gallica — Bibliothèque nationale de France
Pre-1900 digitized monographs and public-domain EPUB manifestations, with ARK and related BnF identifiers, dates, creators, subjects, languages, publishers, physical descriptions, rights, reader and IIIF access, multiple provider image resolutions, edition statements, and exact OPDS acquisition links.
Discovery combines 73 controlled French OPDS queries with a separate, paginated historical SRU harvest using controlled multilingual title-or-subject terms, an explicit pre-1900 date limit, the monograph filter, and Gallica's documented fayes free-rights filter. Metadata must contain the exact controlled term locally. BnF documents that the OPDS EPUBs were produced from public-domain works. OPDS updated timestamps are not treated as original publication dates; IIIF manifests, reader pages, and EPUB files are not misreported as PDFs.

Discovery uses the public MediaWiki search API with 16 German title terms. Only top-level main-namespace pages linked to concrete Wikidata book-like entities are retained; poem, article, short-story, and encyclopedia-entry category hits are excluded. Reader pages are public landing pages rather than direct-file claims; underlying-work rights must be checked on the page.
