Naturally, these are all in the Toronto area. There are many academic titles here, including lots of political science, and some on the philosophy of the physical sciences. There used to be some decent computer science books, but that has faded fast in the last few years. There's also a good stock of children's books. All the books here are donated by alumni.
Many titles are out of date, but there are some real gems to be found.
Lots of history books, and a good selection of old science text books. Some rare books. Again all books are donated. Lots of paperback fiction. Many literary titles, science fiction, and mystery.
