Your books from Goodreads
Currently Reading serves two purposes: a pretty profile page for your current reading selection on Goodreads,
and an API microservice that allows you to consume its API with a
JSON response. As an example, here's my current reading list.
Only a few API methods are available, but unlike the official Goodreads API, they all return JSON results instead of XML. There's no need to provide a key, since it's using my own, so please be sensible about the requests you're making. 😘
Alternatively, you could get the package that connects with the API and modify/extend it as you'd like, by going trough it.
