For books check Amazon or your favourite online book store.
Can also have a look at scribd or books.google.
The absolute best book I ever found for AIX is the AIX Survivial Guide from Andreas Siegert. But sadly it stopped with AIX 4.3.3 and there came never a new book out from him. Still very helpful though.
I recommend AIX 5L Administration by Randal K. Michael. Disclaimer: I once worked with the author; but that doesn't mean he didn't write a good book. I think his shell-scripting book is good, too. Mastering Unix Shell Scripting: Bash, Bourne, and Korn Shell Scripting for Programmers, System Administrators, and UNIX Gurus
The IBM redbooks are free for the downloading:
BM Certification Study Guide - pSeries AIX System Administration
www.redbooks.ibm.com/redbooks/pdfs/sg246191.pdf
If you come from a Solaris or generic UNIX background, this might help:
AIX Reference for Sun Solaris Administrators
www.redbooks.ibm.com/redbooks/pdfs/sg246584.pdf
And (almost) everything you ever wanted to know is available from the IBM pSeries and AIX Help center.
pSeries and AIX Information Center
And I would be remiss if I didn't suggest that you Read The Fine Manuals:
pSeries and AIX Information Center
They are tough to read, but there is a lot of good stuff there.
