Cracks me up that OP is trying Anna's Archive before Wikidata, NGL! Both great sources, though.

I recently (a year ago... wow) dipped my toe into the world of library science through Wikidata, and was shocked at just how complex it is. OP's work looks really solid, but I hope they're aware of how mature the field is!

For illustration, here are just the book-relevant ID sources I focused on from Wikidata:

  ARCHIVERS: 
  Library of Congress Control Number    `P1144` (173M)
  Open Library                          `P648`  (39M)
  Online Computer Library Center        `P10832` (10M)
  German National Library               `P227`  (44M)
  Smithsonian Institute                 `P7851` (155M)
  Smitsonian Digital Ark                `P9473` (3M)
  U.S. Office of Sci. & Tech. Info.     `P3894`

  PUBLISHERS:
  Google Books                          `P675`  (1M)
  Project Gutenberg                     `P2034` (70K)
  Amazon                                `P5749`

  CATALOGUERS:
  International Standard Book Number    `P212`
  Wikidata                              `P8379` (115B)
  EU Knowledge Graph                    `P11012`
  Factgrid Database                     `P10787` (0.4M)
  Google Knowledge Graph                `P2671` (500B)

No, right now you need an ISBN to search for a book. At a later date I'll implement search by title or author, which should help with this use case.

We don't support POST, PATCH, and whatnot yet so I didn't take that into account yet, but it's in the plans.

Still need to figure out how this will work, though.

Thanks! It's a compilation of several random comments I made for a few months, haha.

A couple years I looked for a similar service and failed to find it. I did however find this incredible podcast network called New Books In where they interview authors about their new books. It's a massive network that's broken down by categories that can get pretty niche. Everything from "Digital Humanities" to "Diplomatic History" to "Critical Theory". Episodes appear in multiple categories so broad categories like "Science" also exist

It's definitely biased towards academia which I personally see as a pro not a con

If the data is present in one of the extractors, yes, but I think only Amazon and similar stores keep this kind of data right now. We don't have a extractor for Amazon yet.

After v1.0.0 is out I plan to add the ability to add books manually to the database, at which point we'll be able to start improving the database without relying on third-party services.

You can get an RSS feed from https://bookfeed.io with authors you want to track. Been using it for years at this point :-)

Hardcover and ISBNDB have a good amount of data, with Hardcover being excellent for getting good covers and genres.

I'm hoping Goodreads and Anna's Archive will help fill in the gaps, especially since Anna's Archive have gigantic database dumps available[1].

I only tested English and Brazilian Portuguese so far, and Brazilian Portuguese worked, with translator information included.

Feel free to do so, just keep in mind that the demo server might be unstable and can break at any moment, haha.

I wrote a Go SDK[1] for the service, maybe I'll try writing one in TypeScript tomorrow.

No hug of death, the server is sitting at 3% CPU usage under current load; it seems someone found a bug that triggered a panic, and systemd failed to restart the service because the PID file wasn't removed. Fixed now, should be back online :)

I didn't look into it yet because I assumed the current extractors had the information from them, but it's in my list of future extractors!

First time I'm seeing it, to be honest, but it looks interesting. I do plan on having an UI for Librario (built a few mockups yesterday[1][2][3]), and I think the idea is similar, but BookBrainz looks bigger in scope.

I could add them as an extractor, I suppose :thinking:

Doesn't seem to have a very compleat dataset --- the first book I thought to lok for, Hal Clement's _Space Lash_ (originally published as _Small Changes_) is absent, and I didn't see the later collection _Music of Many Sphere_ either:

Right now the meeting happens on the fly and then is cached. In the future I imagine the finished merge will be saved as JSON to the database, depending on which is more expensive, the merging or a database call.

Merging on the fly kinda works for the future too, for when data change or for when the merging process changes.

No idea what the future will hold. The idea is to pre-warm the database after the schema has been refactored, and once we have thousands of books from that, I’ll know for sure what to do next.

TLDR, there is a lot of “think and learn” as I go here, haha.

No, I decided pretty early on to make it database specific instead of more generic, so we do use some PostgreSQL features right now, like their UUIDv7 generation.

But once the database refactor is done, I wouldn’t say no to a patch that made the service database agnostic.

It seems someone found a bug that triggered a panic, and systemd failed to restart the service because the PID file wasn't removed. Fixed now, should be back online :)
