Finding Genealogy Resources at Half Price Books

As I continually educate myself on genealogy research I find having my own personal genealogy library very helpful.  I have been to many genealogy lectures over the years and they always talk about their own personal libraries and how invaluable they are.  So I decided I needed to start a collection too.  However I can't buy them all at once so which ones should I buy first?  At Genealogy. com I found a great article that gave me the answer.  You can see the article here:  Top 10 Genealogy Books

Well today at Half Price Books I found the #1 book on the list!!!  and a couple others that looked interesting and at the right price.
