Q. The book I need is located in N2. Where is that located?

N2 stands for north wing, second floor.  Just take the elevator to the second floor and head to the back of the library.  Books from A to N are shelved there.  On the sides of the rows, you'll find the ranges of call numbers shelved on that row.  Look for the CB section and then the 351 area and just keep drilling down until you find that complete number.  You can find our library layout map here.  Please let someone at the Reference Desk know if you still need assistance finding the book.
