The one with which I'm most familiar is part of the Great Illustrated Classics series that takes well-known (and public domain) novels and repackages them for young readers, simplifying the stories and adding illustrations on every facing page. We have a shelf of them, and I've enjoyed reading them aloud to my kids (my oldest son's favorite is Journey to the Center of the Earth). And we've read both Finn and Tom Sawyer. Finn was published in 1990, and to my knowledge has never stirred the least bit of ire.
Now I admit, in reading Sawyer, it annoyed me that villainous Injun Joe was now "Crazy Joe." I understood the impulse to change it, but I disagreed with it. Similarly, in their version of Finn there's no "N word," and the dialogue has been rewritten so that no one-for-one substitution is needed. Jim is a slave, and that's enough.
So why all the outrage about this new edition that boldly goes where...well, many have gone before?
Probably for two reasons. First, the recent release of The Autobiography of Mark Twain, a volume he stipulated could only be published a century after his death. It's both a best seller and a critical darling, so Twain is back in the public eye.
And two...well, now there's the internet, and people on the internet love to be offended. Any time there's an issue like this, people rush to show how outraged they are, in a pile-on usually as distasteful as whatever the original offense might've been.* You can see some of it here and here. Even Roger Ebert, who should really know better, chimed in with a particularly crass and tasteless tweet.
Yes, rewriting Finn bugs me, but I'll respond in the proper adult fashion: by not buying this edition. That's all any of us need to do, to register our disapproval. I won't rant and rave about the greater social ills its existence reveals, or try to show how much more it offends me than it does anyone else.
I'm not defending this editorial bowdlerizing by any means; I disapprove of it, and think the concepts behind it are both shallow and wrong. But it's not real censorship as long as the original text is available. And I'm pretty sure it still is.
*(And yes, I recognize the potential hypocrisy in saying this in the context of a post that could be interpreted as doing exactly that. If you think so, please disregard anything I say.)
