Old (2000) Peter Norton books still Worthwhile?

[WWGD]

Hi,
I saw a couple of Peter Norton books: Linux , Java, How to Repair PCs on sale, for about $3 each. Are they still, being this old, worthwhile as a reference, and in general to learn those topics, or are the books likely outdated? Fortunately I can afford the ~ $10 for the three books, but I prefer not to end up with dead weight in my place.

Those books are pretty old. I don’t think you’ll find anything interesting there unless you’re playing with a machine that still runs the OS they are based on.
