Our public libraries are awesome founts of free knowledge, but did you know you can access them without the whole “public” part? The phone apps Hoopla and Libby by OverDrive—the latter introduced only six months ago—offer instant access to your library’s digital content. Simply type in your library card number, and boom—you can stream movies and music to your TV; listen to audiobooks on the go; and swipe through comics or books on your phone or Kindle. Both are free to users (the library pays a small fee per download), and the books automatically return on their due date (unless you click to renew). Both Hoopla and Libby have super-accessible interfaces, making it easy to browse by type, genre, popularity and more. Libby has more functionality—you can put books on hold and input multiple library cards—but Hoopla has the better comic book reader. Why decide? I use both.
