HarperCollins Publishers and Waterfront Media have partnered to launch online content based on HarperCollins' authors and titles.

The collaboration allows consumers, through subscriptions, to access exclusive content online. 

"This agreement is another example of our Publishing+ initiative, Author+, and how we continue to bring value to our authors through creative partnerships. Waterfront Media is the leader in marketing and monetizing book brands on the web. Working with them allows us to extend our author and book brands online, an increasingly important component of the publishing process," says Brian Murray, group president, HarperCollins Publishers.
