Calibre used to offer an official douban plugin to fetch the book metadata from douban.com. However, the author of Calibre chooses to not maintain it any more. So I decide to maintain my own branch.
In order to work functionally, this project requires a valid API key. The project itself does not provide any API key and does not recommend to share any API key in any method. Please use your own API key or contact bd-team@douban.com for authorized access.
