I created this resource to explain what Interactive PDFs are and how to use them on computers and iPads. There are brief descriptions accompanied by pictures for opening an interactive PDF on both Adobe Reader (Mac and PC) and Apple Books (iPad). I've also provided links to some suggested PDF reader apps on the Apple Store and Google Play.
