Hello my name is Brian and I will be attending this sept 2014  class. I saw newer version of 
&quot;Doing Right: A Practical Guide to Ethics for Medical Trainees and Physicians Paperback – April 15, 2009 

by Philip C. Hébert (Author) &quot;  the 3rd edition for 2014. Are we allowed to purchase this version or do we have to stick with the older 2nd edition 2009 version?

thanks Brian
