Library Extension is a free Chrome add-on developed by Quotidian LLC. This handy tool allows users to easily access library catalogs and check the availability of books, music, and audiobooks as they browse various websites. With support for over 5000 libraries worldwide, users can instantly see the availability information for their desired items right from their browser.

The main feature of Library Extension is its ability to provide instant availability information. As users browse different sites, the add-on automatically detects book, music, or audiobook titles and displays whether they are available in their local library's catalog. This eliminates the need for users to manually search for items on library websites, saving them time and effort.

To ensure a seamless browsing experience, Library Extension provides a complete list of supported libraries on its website. Users can easily check if their local library is supported by visiting the link provided. If their library is not currently supported, users can provide feedback to the developer through the feedback page, and the developer is always happy to add new libraries.

With Library Extension, users can conveniently access library catalogs and check availability information without leaving their browsing session. This add-on is a valuable tool for book lovers who want to make the most of their local library's resources while browsing the internet.
