That is a great find. With the 2009 through 2015 catalogs you have an option of an actual catalog and "view as HTML." The HTML version is simply a page of links to the product page of each item. Unfortunately, for those years Adobe Flash is required to view the catalog. Flash reached end of life in January due to security concerns. For several months users saw prompts to uninstall Flash when visiting a page with Flash. I am not sure but I believe eventually many browsers uninstalled it for you. You can no longer download the Flash Plugin. I just tried Safari and Chrome and neither would display the catalogs.
