[14] Three months later, it sold its library assets to OverDrive, Inc.; this includes RBDigital, an app and service for the distribution of digital content.

The sale of RBMedia's library division to OverDrive represents a merger of KKR's related assets.

The catalog includes audiobooks from the previous acquisition of Gildan Media and McGraw-Hill Professional.
