Footnotes, endnotes or online notes?

[BettyO]

...it would not make any sense for me to read (unless it's fiction) if I can't highlight or make notes.

I, too am an avid note taker, Eva. As was John C. Brennan. The books from his library are a virtual treasure of note-taking. Don't ever ask to see the paperback version of my copy of American Brutus! My hardback was a gift from Mike Kauffman and I don't make notes in most of my hardback copies; which is usually why I have two copies - one paperback and one hardback of each book unless I can't find a paper copy. A lot of times, I use "sticky notes" to mark pages and passages so as not to mar the book.

I like eBooks, too; but Geek that I am, I still prefer a good old hard copy!
