As we’ve previously shared, 2016 was a record breaking year in digital library lending, as readers borrowed 196 million books through OverDrive-powered library websites. This 21% overall growth can be attributed to an increase in digital circulation across countless OverDrive library collections around the world. In fact, 49 individual library systems and consortia surpassed one million checkouts in 2016, up from the 32 that reached that milestone in 2015.

These digital collections span across three separate countries, with 30 being standalone public library systems and 19 being consortia. Below you’ll find the full list of our “Million Checkout Club” members. At the American Library Association winter meetings, OverDrive will present on the technological advances coming in 2017 that library partners can take advantage of with anticipation towards breaking this new record once again in 2017.
