    MyBookshelf

    MyBookshelf

    Read online content from customized sources

    MyBookshelf is an open-source Android reading app (known in Chinese as “阅读”) that lets users configure custom content sources to read web novels and other online text, offering a flexible alternative to fixed, vendor-controlled ebook stores. Instead of depending on a single provider, it uses “source rules” that define how to search, parse, and fetch chapters from multiple third-party sites, giving users control over where and how they obtain content. The app focuses on delivering a comfortable and customizable reading experience with options for themes, fonts, layouts, and reading behaviors, tuned to the preferences of heavy web-fiction readers. A disclaimer in the project makes it clear that the app itself only provides search and reading tools, and that responsibility for accessed content lies with the user and third-party sites.
