One Of The Colleges I Went To...One of the colleges I went to hadn't updated their library (much to the science students' dismay). I used to love going in there and looking at old books. There were some from the 40's and 50's and maybe even the twenties. I liked imagining the people who'd used these books when they were still new.
In general, I prefer used books. I like being able to read the notes that someone else has written in the margin and sometimes finding pictures and notes intentionally placed in the book for the next reader. Good stuff!
