Give your book a bookend.
Mint a permanent, content-addressed identity for your work and open a public room where readers can sign in, talk back, and trace its lineage. The whole thing takes a few minutes.
Why register a bookend?
A book exists. A bookend gives it a public home.
Under the Berne Convention you already hold the copyright the moment you fix the work in tangible form. What you don't get is a public, dated, verifiable record of what the work is and when it existed — and that's the gap that matters when something is disputed, cited, or rediscovered years later.
A bookend closes that gap with two things at once: an IPFN — an InterPlanetary File Number that hashes the work's metadata onto a permanent, decentralized network — and a public room at /book/your-title where readers can sign the guestbook, ask questions, and watch the conversation grow.
What you get
Certificate of publication
A real IPFS cert pinned at registration. The hash is the receipt — anyone can verify the work matches it, and that the hash existed on the date.
A public guestbook
Readers leave inscriptions tied to your bookend. The room never closes; the entries form a living archive of the book's reception.
Table-talk threads
Threaded conversations that live alongside the guestbook — for questions, critiques, study notes, or extras the cover can't hold.
Identity + provenance badges
Real publisher metadata, ISBN, edition, source attribution (Project Gutenberg, Standard Ebooks, your own press) surfaced as durable badges on the cover.
