Self-studying Psychology. 2006 vs 2007

<p>Ok so I'm self-studying Psychology next year and am thinking of getting Barrons.</p>

<p>Amazon has the 2007 version, but my library carries the 2006 one. Is there a noticeable difference in the 2007 version that it'd be better for me getting it?</p>

<p>In every new edition, something is improved, so newest would be best, but the 2006 one will definitely work for you.</p>
