No hash is published. This build does not store those PDF bytes, so a checksum would be invented. Where a legacy path exists, it points at the Internet Archive copy of the old library.

Direct answer

Each token id has an owner. Transfer moves that id. An optional metadata URI points at a description. The standard does not say the description is true, or that the object exists off-chain.

Where to read

Metadata and commentary only. The reading is the study page.
