Suggestion: Use Calibre to get book metadata

[humCopper]

Why not use Calibres' fetch-ebook-metadata to get the books' information. It will simplify adding book because you will only need a title to get information from a book instead of using a URL from Amazon or Goodreads. Also, it will allow you to get a lot more information on the book.

Sure, that will be useful. I will try adding a basic (only title based) search in some time.

Another useful opensource tool to get the metadata from is fanficfare:

fanficfare --non-interactive --meta-only --json-meta 'https://www.royalroad.com/fiction/21174/vacant-throne'
