图书馆助手 is a Chrome add-on that provides support for connecting resources from popular book platforms such as Douban, Dangdang, Amazon, and JD.com with your library. This tool allows you to view your school library's collection directly on the book pages of these platforms.

The latest update, Version 5.1, has fixed the issue where new users were unable to use the tool. It also includes optimizations for faster response times and introduces a feedback channel. Users can now provide feedback within the extension itself, eliminating the need to email the developer with their school information.

With Version 5.0, the developer has made several major improvements. Firstly, the school selection interface has been enhanced as promised. Secondly, the configuration file has been separated to facilitate support for multiple systems in the future. The interface has also been beautified, and logic errors specific to the current e-commerce platform have been fixed.

Overall, 图书馆助手 is a useful tool for students and book lovers, allowing them to seamlessly connect their favorite book platforms with their school library resources.
