Google brought some of the tablet magazine experience to shopping catalogs on Tuesday with the rollout of Google Catalogs for the iPad (free, App Store). The release recreates the layout of print catalogs like Bergdorf Goodman, Lands' End, and Urban Outfitters but takes advantage of the tablet to blend some of the web experience. Readers can either buy directly from the catalog owner online or find out whether it's available in a physical retail store nearby.
