If you are a developer or relay admin, and want to make sure that your client or relay can handle the #bookstr macro, I would suggest you read the spec [[NKBIP-08]]:
https://wikistr.imwald.eu/nkbip-08*645eb808ac7689f08b5143fbe7aa7289baad2e3bf069c81d2a22a0d3b3589c18
We are going to be publishing a LOT of books and other important documents, so it would be a shame if you missed out. Make sure to follow nostr:npub18cddpua960qjy3wmw7y9gmzr4h3ajlrwq3k9jnmqzlxke4qkg6gqeyaztw , so that you can see everything it writes, or look on #Alexandria:

nostr:npub1wqfzz2p880wq0tumuae9lfwyhs8uz35xd0kr34zrvrwyh3kvrzuskcqsyn is helping me hone the spec and make it as AI-friendly, as possible. If anything is unclear or incomplete or simply wrong, just @ me. 🤙🏻
