Hello, I've been trying to find resources to learn about Linux so I can be confident about its use before installing OpenSUSE. I found two books listed below and uploaded PDF files of both of them. If any of you have read these books before, or have read the linked files enough to get a solid opinion, I am interested in hearing if you believe that these are legitimate learning tools or something that will just gather dust. Thank you for any help you can offer.

I'm sorry if this is the wrong section. Between this and the ebooks section and the OS section, it seemed this was the safer bet if I wasn't sure.
