Cisco reparation Library or Certification Library?

All,

I am going to start studying for my CCNA. I have a few years of networking experiance and need to get this certification to contonue on my voice and security paths.

I am in the process of choosing books to help me get the cert.

Cisco Press has two librarys to help get certified, and I cannot pick which one would be the best to use. The Links are as follows:

CCNA Prep Library - http://www.ciscopress.com/bookstore/product.asp?isbn=1587054647

CCNA Certification Library - http://www.ciscopress.com/bookstore/product.asp?isbn=1587201836

Any help on these two compared would be great.

Thanks
