Scribd officially launched its new ebook subscription service in conjunction with HarperCollins. It’s an all-you-can-read subscription for $8.99 per month, and now competes with eBook service Oyster, which launched just over a month ago. Scribd has, apparently, secured the bulk of HarperCollins’ catalog, and claims to have books from over 30 other publishers, including “thousands” of bestsellers. HarperCollins apparently chose Scribd because it already has the ability to reach large markets and build audiences at scale, rather than starting from the ground up, like Oyster. Scribd is offering the first month free as a promotion at the time of writing.
