JMRL has a single catalog with two different interfaces to access and experience the entire collection.
Classic is the base interface provided by the catalog vendor. It is a simplified experience for users who do not wish to see a lot of additional content.
Find It is a modernized interface built in an open-source application. It is an updated experience similar to more current catalog websites with large book covers, carousels, and full integration in JMRL's website
