From our eBook vendor Overdrive:
Penguin titles will no longer offer additional copies of eBooks and download audiobooks for library purchase.
Additionally, Penguin eBooks loaned for reading on Kindle devices will need to be downloaded to a computer then transferred to the device over USB.
For library patrons, this means Penguin eBooks will no longer be available for over-the-air delivery to Kindle devices or to Kindle apps.
How will you know you have a Penguin eBook?
On your title’s page, look at the Publisher line.
