Abstract: A system and method of browsing electronic catalogs from a plurality of merchants. The electronic catalog system emulates the portability and usability of a traditional paper and ink catalog, especially when realized on a tablet or mobile device. Product data feeds from multiple merchants are collected and processed to build a product database. A server retrieves product data and serves it to users browsing the electronic catalogs. Users can request more detailed information and order products through the server and merchant websites. Users communicate with the server and merchant websites either through a standalone software application or via a standard web browser. Merchants are able to update the contents of their electronic catalogs through a merchant portal.
