Answer: 

You can check out books over break provided the check-out period is long enough (i.e. Course reserves, on a two-hour check-out period, would not be available over break.)  Keep in mind that books are subject to recall, which means another patrong might want to use that book. When a book is recalled you will need to return it within 2 weeks. If you are away from campus, this may mean shipping the book to the library.
