“Librarians and educators pivoted to provide ebooks and audiobooks to all readers when their doors closed and school became remote,” Steve Potash, founder and CEO of OverDrive, tells Fortune.

At first, juvenile and young adult titles were a priority, Potash explains, followed by readers “seeking to comfort, educate, and delight themselves during their shelter-in-place periods.” He notes this led to a surge in demand for cookbooks, gardening, and other hobbies and crafts.

“Millions of seniors and other first-time users discovered and downloaded their first ebook and audiobook as a result—and they are now trained and sticking with the digital book option, thanks to the investments made by librarians and educators,” Potash says.

For business readers, here’s a rundown of the most downloaded ebooks and audiobooks at public libraries with access to OverDrive in 2020.
