BookStairs is an open-source personal EPUB library which was highly inspired by talebook, calibre-web and BookBrowser.

It's designed to serve millions of books. Aims to provide high performance, readability compared with its competitors. And it's easy to be deployed on any Unix-like systems by docker.

• High performance

BookStairs didn't use metadata.db which was created by calibre directly. We would index all the books' metadata by bluge which can provide a better searching performance comparing to SQLite3. Although bluge isn't fast enough compared to elasticsearch, it's fast enough to serve the book indexing in memory mode.

• Better book organize

The books' category is defined by the Chinese Library Classification. Putting all the files into SeaweedFS for fast file access. This will make the S3 support out of box.

• Better book deduplication

We would deduplication the book by its CIP (Cataloging in Publication) in China and ISBN.

• Better chinese books metadata management

A lot of Chinese EPUBs don't have valid metadata. We would correct it by CIP database and a builtin Douban spider.

• Readability

We provide a built-in online reader which supports bookmarks, quotes, notes and highlights. Every user could have unlimited bookshelf for personal needs.

• Easy distribution

The bookstairs was designed to be distributed with only one file on all the platforms. You don't need any predefine configuration file. Just download the latest release file and execute it in a working directory. The bookstairs would auto create the database and application data files by your settings on a user-friendly web interface.

The current master branch is unstable and is not recommended for production use. BookStairs 1.0.0 (what will be the first release version) is currently in the development stage.
