The e-book subscription service, Scribd, announced yesterday that it was adding auidobooks to its arsenal. For the regular $8.99 monthly subscription fee, users of the “Netflix for books” will now have access to over 30,000 audiobooks in addition to Scribd’s standard collection of e-books.

“Audiobooks have been one of our most requested features since the day we launched,” the company said in a blog post. “Today we’re so excited to say they’re here.”

Of the three main e-book subscription services – Amazon, Scribd, and Oyster – Amazon was the first to include audiobooks as a standard part of its service. But with only around 2,000 audio titles, Amazon’s “Kindle Unlimited” seems to treat audiobooks more like an add-on. For the main event, Amazon wants users to shell out an additional $14.95 per month for Audible.  Thus, the sheer number of titles Scribd is offering has the potential to be a game-changer. While still only a fraction of the 150,000 titles available through Audible, 30,000 plus for no additional charge is nothing to sneeze at.

“Audio is a growing category and one that needs additional distribution channels,” said Chantal Restivo-Alessi, chief digital officer of HarperCollins Publishers, in a statement, according to Forbes. “By making our audiobooks available through Scribd, we’re opening up a much wider market for our authors’ works.”

For now, HarperCollins is the only one of the “Big Five” publishers (including Hachette, Macmillan, Penguin Random House and Simon and Schuster) to directly licence with Scribd on unlimited streaming, Forbes reports. However, through an agreement with audiobook company, Blackstone, the service will have select titles from all five. And the lineup is impressive. Suzanne Collins, Elmore Leonard, Dennis Lehane, and Cormac MacCarthy are just some of the authors boasting about by Sribd.

According to the Forbes report, audiobooks represent a $1.7 billion industry.
