IBM Redbooks

At work we are entirely an IBM shop. All our servers (and desktops for that matter) are IBM. I recently found an excellent free resource over on the IBM site. Its their redbook series of papers and books. They have a whole section dedicated to linux also. You can view them as PDF or html and they are free to download., and they have an RSS feed too. Currently Im reading though their "Linux Client Migration Cookbook A Practical Planning and Implementation Guide for Migrating to Desktop Linux" paper, and it seems very good.
