It's a very nice place. Can get almost all the work done (printing, scanning,etc). 4rth floor is the best place to sit and study. It's very calm and almost deserted.
If you like books, then this is the place for you. They have over two dozen books for you to look at, check out, or read!!! Tell'em Mitch sent ya and you'll get sweet deal on a book.
if you are looking for a quite place to study (or nap) the 4th floor has the most comfortable lounges with a wonderful view of the library lawn. But be respectful, as it is a silent study area.
Checkout more than books with your OSU ID! There are 160 laptop computers and 20 MacBooks and 30 iPads which can be checked out for 5 hours each as well as e-books, DVDs & CDs.
