License study materials
Tim,
I found that the Hennepin County Library has a good selection of instructional books. The one you want, or at least what I and many people used, is called The ARRL ham radio license manual : all you need to become an amateur radio operator / by Ward Silver. Your library up in Princeton can get this through Interlibrary Loan. Cost: free!
The link in the sticky, "Where to take the exam" works great. I took mine with the Bloomington VE group, and found them to be friendly and well-organized, though I would expect that most test sessions are that way.
Good luck!
