I would like to find the same thing for online ebook/textbook readers that University websites use. Suggestions? Every online reader I've used ProQuest, VLE, BCR, etc offer the worst online readers with frames, annoying 15 minute timeouts, terrible highlighting/notes, etc I just want to print or download a local copy to highlight & full text search offline (I run them through OCR for text)
