AddLinks by Thomas Persson Christensen

The internet was supposed to be a web of links, not a collection of walled gardens.

AddLinks restores connectivity to the book world. It seamlessly connects independent book sites, libraries, and retailers, allowing you to jump freely between them. If you find a book on StoryGraph, you should be able to check if it's at your local library or cheaper at a competitor with a single click.

This extension detects ISBNs on the page and automatically injects deep links to other platforms, breaking down the walls between book sites.

NOTE:
Amazon is supported but disabled by default. We prefer to support independent bookstores and libraries, but the option is there if you need it.

Supported Sites
International: Goodreads, The StoryGraph, Instagram
Danish: Bog & Idé, Antikvariat.net, Bibliotek.dk (all Danish libraries), MinReol.dk, Litteratursiden

Project Focus
The extension currently has a strong focus on Danish book sites and libraries, but we are actively working on adding more international sources and targets to make it useful for a wider audience.
