This is a fantastic article. I have also learned so many things just teaching myself through books (even before the internet). I taught myself how to play the guitar by buying Mel Bay’s book of chords. It’s amazing how many songs you can play with just three or four chords. Actually, Hank Williams is quoted as saying that if you play more than three chords you’re just showing off. Ha, ha.
I learned Spanish through Pimsleur and then moved to Chile for 6 months. (Helps that I live in L.A.). And I learned HTML programming through a book, “HTML, The Definitive Guide.” That was before Dreamweaver or anything like that. It’s helped me in other things.
Anyway, thanks for sharing all your resources!
