MPS Technologies', a company that provides technology-driven services for publishers and librarians, has upgraded its BookStore platform with features that address the new challenges the book industry now faces--as Web 2.0 revolutionizes the way publishers market books to their readers. BookStore is a digital platform that stores, displays, and sells eBook content. BookStore allows publishers to make their content available online and provides them with different business models to choose from. New features on the platform now include the MPS Technologies Widget--a viral marketing tool that enables readers and authors to place book content on social networking sites globally. BookStore is now fully integrated with social bookmarking sites and clients are also able to update their readers on new titles via RSS feeds and email alerts.
