We had another record-setting year in digital reading, with libraries, schools, colleges and companies circulating half a billion titles through OverDrive in 2021. We also had a record 121 library systems surpass one million digital checkouts in 2021. This includes 22 library systems hitting this milestone for the first time. In total, 506 million ebooks, audiobooks and digital magazines were checked out by readers last year.

Libraries continue to provide a vital service to their communities during the COVID-19 pandemic. Readers around the world discovered or rediscovered a love of reading thanks to digital collections, which allowed them to safely seek and enjoy books from home. Digital book clubs like Big Library Read connected readers from across the globe and we look forward to getting more books into the hands of more readers through our digital book clubs so mark your calendar for our 2022 dates!
