Preservation

Materials Preservation Program

Every digital copy is stewarded under explicit rights, readability checks, OCR status, and a long-term preservation plan.

Mirrored archives

Every title in the Discussion Publishers Library is preserved with redundant copies of HTML, EPUB, plain text, and cover art, and assigned a permanent library number and ISBN.

License verification

Each title carries an explicit license tag. Downloads are gated by the license: public-domain titles can be downloaded without restriction; restricted items are read-only.

Provenance & audit logs

Staff curation, submissions, approvals, and downloads are recorded in an immutable audit log.

Open access by default

Catalog metadata is exposed via stable URLs (/book/<id>, /authors/<slug>) and indexed by search engines wherever rights allow.
