I am currently studying for a certification with my employer. The study materials I was given for the certification came in a hard copy form as well as a CD with HTML files (there is index file with hyperlinks to each chapter). I was curious to know if there was a way to take simple HTML files and convert them into ePUB files. Since the information is so voluminous I would love to have an iPad version to study when I travel. I am also under the impression that ePUB files on the iPad can be highlighted? Thank you!
