Edelweiss is essentially an interactive platform on which publishers post their seasonal catalogs, along with backlist catalogs in most cases. There are tools for communicating with sales reps, creating and managing orders, communicating with your staff, downloading e-galleys, writing reviews, filling in Event Grids and much more. This is the platform in which your Edelweiss Analytics tools live.
