I like books and to save money I started buying used ones off Amazon. You can find some really good deals and even though it takes a few days or weeks to arrive you never really know what you are going to get.
Today, Benjamin Franklin by Walter Isaacson arrived and when I opened it I found tons of underlines and markings from the past owner.
To me it doesn’t really take away from the book. Instead it’s like some random person whom I’ve never met is showing me what is important to them. I think it’s rather cool.
I might feel different if I paid a lot but this particular book was only around $5 including shipping, plus it’s only in pencil so I could always erase it if I wanted.
