Same here. But I guess this will come in handy in the future. Thanks

I use StoryGraph for my personal library management, but Goodreads simply has better coverage of both total books and specific metadata. But Audible is the best source anyway, as it has data specific to the audiobook other sources rarely do. I've included Goodreads mostly as a fallback for books Audible doesn't have listed. One of the roadmap items is to add other sources, like Google books. At that time I would consider a source separate from Amazon/Google if a quality one can be found and conveniently called/scraped.

FWIW, they don't have an api. It's on their long term roadmap.

It can do some metadata matching, but to my knowledge it doesn't do any of the big ticket items like combining chapter files

Metadata is written to the file at the time of operation, so Goodreads failing would not affect any existing metadata sourced from it. But Audible is the preferred source anyway, as it has metadata specific to the audiobook typically not available in Goodreads. I've included it as a backup for books (mostly older ones) that are not available on Audible. Goodreads allows user submissions and thus has just about every book available in its library.

You should be able to manage that with a .cue if you’re playing from Plex or AudioBookShelf. I think Jellyfin supports them too
