We're publishing books, for about a year, so far.
Mostly Bibles and British classics.
This is the spec I use for the book-wikilinks.

The wss://thecitadel.nostr.com is a public document relay, where we publish our kind 30040 publications, and I included it in the #Quranstr defaults.

We're also going to publish the Torah and Quran, with the appropriate book-wikilink tags, so that you can embedded them in events.
