Got these two old textbooks from one of the hall buildings at the university
So, basically, this hall building is gonna be demolished this summer. So, I grab plenty of books from there including these two books. The book on the right was grabbed yesterday. The book on the left was grabbed 7 days ago. Old textbooks are so cool as references.
