The Maken Similarity Service is a browser extension developed by the National Library of Norway AI-Lab. It seamlessly integrates into the search features of the main nb.no site, providing users with an enhanced search experience for books and images.

With this extension enabled, users will notice a new button for each search result in the books and images categories. These buttons are labeled "Lignende gjenstander" (Norwegian for "Similar items"). When clicked, a section at the bottom of the screen opens up, displaying a list of similar items to the one the user has clicked on.

The displayed elements are clickable links that allow users to explore specific related items further. This new discovery tool, developed by the AI Lab at the National Library of Norway, provides users with a convenient way to find related content without having to leave the main library website.

Overall, the Maken Similarity Service is a valuable addition to the nb.no search experience, offering users an efficient method to discover similar books and images within the library's vast collection.
