Few yet understand this, but #Alexandria, in principle, makes every publication following the NIP-62 format uniquely addressable online.

If I provide you the Alexandria URL for a publication, you can verify its authenticity by confirming that the publication's Nostr event was signed by the entity that has the rights to publish it. This cryptographic identity cannot be faked. If changes are introduced, such as by the publication of a new edition, this too can be verified using Nostr identities.

It's like every possible publication that could be created has a street address, and you can go knock on the door and see for yourself that the person who is supposed to live there is indeed the person who answers the door.

We've not yet scratched the surface of the impact this new reality will have.
