markups for mobi, pdf or epub

I like to buy books online that come in three formats. ePub, Mobi and PDF. What I'd like to be able to do is highlight the parts that are note worthy to me and perhaps add notes of my own. I'd love it if that info could be stored and retrieved later on. Kind of like the functions you'd get if you were reading a kindle book if you're familiar with that. I'd like something like that for any of the three formats.

Is there something like that in the repository?
