I drove 900 miles to my new school last month, and, luckily, I was able to fit all of my books into my small car. Last year, however, I moved out the the country and had to condense my large book collection in order to leave it in storage at my mother's house. I wound up getting rid of about 300 books. I decided to get rid of classics which would be very easy to inexpensively replace if I ever wanted/needed another copy. I also decided to part with books totally unrelated to my proposed studies in 20th century American literature. I didn't forsee needing a copy of any of my medieval, early modern, or pre-Romantic books, so I tossed those out as well.
