Wow, I've done some unintentional good work with that thread!
Yeah, the Project Gutenburg link is great. But I still love my Ballantine paperback copy with the Neal Adams painting of Tarzan leaping out of the trees with his knife to attack Terkoz, who stands their bellowing back at him and loosely holding Jane by the hair in one hand. To me, that's the iconic Tarzan image right there; savage yet righteous fury personified.
You read that quick, though--you should definately check out
The Return of Tarzan and close the loop on that story arc, though.
I honestly think that ERB didn't intend to continue Tarzan past those two books, but his popularity was so incredible that he ended up milking it for some 24 books or so (the last published posthumously.) They do tend to get into a rut of sorts, though--it's not really worth it reading all of them unless you really have a lot of time on your hands (plus they're not all available at PG.)
Tarzan and the Ant Men is considered by some to be the best of the "mid-series" Tarzan books, though--following the formula, but doing it with style before it got tired.
Tarzan at the Earth's Core is also an odd book, but it's one of my favorites; the breadth of imagination in there is amazing. I've also really always liked
Back to the Stone Age a one-shot spinoff book from
TatEC.
Oh, did I mention that I'm kinda an incurable ERB fanboy?
