<p>What’s the difference between:
[Amazon.com:</a> Multivariable Calculus (Paper) (9781429210690): Jon Rogawski: Books](<a href=“http://www.amazon.com/Multivariable-Calculus-Paper-Jon-Rogawski/dp/1429210699/ref=sr_1_1?ie=UTF8&s=books&qid=1252611967&sr=8-1]Amazon.com:”>http://www.amazon.com/Multivariable-Calculus-Paper-Jon-Rogawski/dp/1429210699/ref=sr_1_1?ie=UTF8&s=books&qid=1252611967&sr=8-1)</p>

<p>[Amazon.com:</a> Multivariable Calculus: Early Transcendentals (9781429210799): Jon Rogawski: Books](<a href=“http://www.amazon.com/Multivariable-Calculus-Transcendentals-Jon-Rogawski/dp/1429210796/ref=sr_1_2?ie=UTF8&s=books&qid=1252611967&sr=8-2]Amazon.com:”>http://www.amazon.com/Multivariable-Calculus-Transcendentals-Jon-Rogawski/dp/1429210796/ref=sr_1_2?ie=UTF8&s=books&qid=1252611967&sr=8-2)</p>

<p>Published on the same date and the same number of pages, but the covers & ISBN are different.</p>
