Startup Oyster Books has introduced a new service that gives readers access to an unlimited amount of eBooks for a $9.95 a month subscription fee.

The service gives readers access to more than 100,000 titles including bestsellers and classics from major publishers on an iPhone app. The company tweeted today that the plan to roll out to the iPad this fall. You can read as many titles as you like. There is even a social aspect, so you can check out the books that your friends are reading.

Self-publishing platform Smashwords also announced a partnership with Oyster last week, so there will be more emerging authors available through the platform as well.

The service is currently only available in beta, but you can sign up to get an invitation here.
