Which one is the Schaum's book everyone likes for the DAT?

Schaum's A-Z Biology (http://product.half.ebay.com/Schaums-A-Z-Biology_W0QQprZ2367142QQtgZinfo)
Schaum's Outline of Biology (Paperback)

Thanks in advance :))

I used Schaum's Outline of Biology (http://www.amazon.com/dp/0070224056?tag=dentalstudent-20&camp=14573&creative=327641&linkCode=as1&creativeASIN=0070224056&adid=1AJFCQ67YTXVC6Q4D468&) and I think thats the book most other students get as well. The A-Z book might be an update since the outline of biology is from like 1998 and the A-Z book is from 2003, but I'm not really sure.
