Libraryboxd is a Chrome extension developed by leozeuli that seamlessly integrates the popular movie-tracking website, Letterboxd, with library services. This free add-on adds disc icons to movie posters on Letterboxd, allowing users to easily access the movie on their local library's website. With Libraryboxd, users can quickly check if a movie is available for borrowing instead of renting, saving both money and time.

The extension works by allowing users to select their library system and branch, and then it automatically scans the library's system to check if the movie is available. If the movie is in the library's collection, a clickable icon appears in the upper right-hand corner of the movie poster. However, if the movie is not currently available at the user's branch, the icon is faded out, indicating that it can be borrowed from another branch.

Libraryboxd streamlines the process of accessing movies from local libraries by providing a convenient link between Letterboxd and library services. With just a few clicks, users can easily find out if their desired movie is available for borrowing, making it a valuable tool for movie enthusiasts who prefer library resources over rentals.
