From a MT News Release:
Midwest Tape and HarperCollins Publishers today announced a strategic library distribution agreement to commence immediately.
The non-exclusive agreement enables Midwest Tape to distribute the majority of HarperCollins Publishers front list audiobook titles to libraries.
A key component of the deal calls for Midwest Tape to manufacture CD editions of HarperCollins Publishers audiobooks that potentially may have only been available as digital editions.
