The present invention is a method and system for electronically distributing digital contents. The digital contents include textual, graphical and pictorial information. At least one portable electronic book is operative to request a digital content from a catalog of distinct digital contents, to receive and display the requested digital content in readable form. An information services system is in electrical communication with the portable electronic book to perform authentication and rendering the requested digital content. An authentication server authenticates the identity of the requesting portable electronic book. A copyright protection server renders the requested digital content sent to the requesting portable electronic book readable only by the requesting portable electronic book. At least one primary virtual bookstore is in electrical communication with the information services system. The primary virtual bookstore is a computer-based storefront accessible by the portable electronic book. The primary virtual bookstore includes the catalog of distinct digital contents and a repository which stores the distinct digital contents listed in the catalog.
