One note on Verne -- a lot of early Verne translations (e.g. the ones in the public domain) have really lousy English translations. Big things, like sections being excised because they seemed anti-England, and little things like metric units not being converted to English (screwing up Verne's careful math). So while it's nice to have them free, you'd actually do yourself a favor of getting a modern translation when available, even if you have to pay for it.
