PDL has a TumbleBooks subscription that can be accessed online through this direct link. Explore, read and have fun! TumbleBooks are animated, talking picture books which teach kids the joy of reading in a format they’ll love. TumbleBooks are created by taking existing picture books, adding animation, sound, music and narration to produce an electronic picture book which you can read, or have read to you. TBL also includes National Geographic videos and games. Users can also access TBL from any smartphone or iPad/Android tablet by downloading the app. Subscriptions are unlimited, meaning your kids can read as much as they want, when they want, with no wait times, check-outs, or downloads.
