Abstract: Shanghai Library has explored many ways in providing e-book services, such as e-book reader
lending, building a reading platform with metadata integration, and developing reading app and related
digital reading hardware. These, however, cannot effectively address the issues of poor content quality,
copyright infringement and less desirable user experience. And now there is a new attempt to enhance the
digital reading experience on the part of Shanghai Library by purchasing and processing EPUB format
e-books independently and using open source software to build its own e-book platform. This paper mainly
introduces the main structure, function modules and related design concepts of the platform.
