Hachette Book Group has signed with Tata Consultancy Services in an agreement through which TCS will provide targeted application and development support services that will help HBG to continue to expand in the digital market. Working with TCS, HBG’s IT staff will expand the company’s web capabilities, continue to optimize its infrastructure and network, and extend its content into new digital platforms. The deal is expected to also result in new products and strengthen HBG’s position in the e-commerce field. At present, HBG sells digital content directly from its site, but not print books.
