References guide your local library often times is a great resource for hard copies of some common and sometimes uncommon books Sent from my C6740N using Tapatalk
Agreed. PLUS - you can use Interlibrary Loan to greatly increase your options. I was able to order a copy of the Kennedy Half Dollar Book through ILL from the Vigo County Library in Indiana - one of TWO copies showing in the library system at the time I got it (the other was in the Library of Congress.)
