I use vitalsource for my eBooks. I don't know about Kno. Vitalsource worked fine for me. I can highlight the sections I need. You can make notes on those highlights as well. You can even organize your highlights with your own titles and choose different colors for each. I had pink highlights for my "reading assignments". I had green for "need to know for exam", etc. Some eBooks don't use the vitalsource format and may show up like web pages. My fundamentals book was like this. The ebooks that use the vitalsource platform are great. They have links that take you to a point/table/page that may be referenced online or in another chapter. There is a search option and you can also enter in a page number and it takes you right to that page. With my med/surg book, one page may span over 3 to 4 pages/swipes because of the size I have the font set to. You have to remember how thick that med/surg book is and how much info they pack on one page in the actual book. You can click on the pics and tables to view them up close. You can adjust the font size and other things too. It also has a dictionary. The ebooks that don't use that format have to be zoomed in or out. They also lack the links that can take you to various references in the chapter. Only one of my books had that problem. You can still highlight and do everything else. It's a little annoying to highlight because the page moves just like a regular web page does on most touch screen devices. Oh I use it with my ipad and even have it on my phone. I have not actually printed anything from within the chapter. I do print out the keynotes at the end of the chapter. I log on to my computer for that. All in all, it works for me.
