It’s strange. When I was in school, the last thing I wanted to do was read and/or take notes, but now I seldom ever read anything (newspaper, books, even websites) without taking notes. So I was pretty pumped to find this site earlier:
Introduction to Book Outlines
It has an amazing selection of notes from a big list of books. Now I’ll look here first before taking notes on a book, and simply add my own notes to the existing outline.
