inherited OLD Linux Red Hat disks

I have a couple of what I think to be old Linux install CD's. It's a two disk set and it says on the CD:

Red Hat Linux 5.1
copy right 1998
by Sam's Publishing and it's licensor's
version 1.0

At the bottom it says:
Unleashed
third edition

The ISBN is 0-672-31372-3cd

Is this too old to mess with if I should decide to fool around with Linux?
I'm afraid of messing up what is finally a good install of XP, so I haven't messed around with Linux at all.

I don't think you have RedHat install disks. I think you have the CD version of the book. See the link below:
