You should always start your search for books with the Pace Library Catalog, which tells you what books are on the shelves at the three Pace Library locations and it tells you what e-books we have access to that you can read online. If you don't find what you need, then move on to other options:
At the Library homepage, click on the "Books & Media" tab:
WorldCat.org >>
If you can't find the book you need in the Pace Library collections, search for it in WorldCat and then request it through Interlibrary Loan.
