[EX Q]: Great American classic that you can get for free on kindle. I was supposed to read this back in high school but wasn't not interested at the time. But now with the benefit of age I can really appreciate it.
[EX A]: Positive

[EX Q]: I had seen this authors' works offered for free on the Kindle page and since the price was right downloaded two of them. I was happily reading "The Lamp In The Desert" when I got to location 2458-61, and there in the middle of the page was the "N" word. Now I realize these books were written in a different time, and people had different morals and people were unenlightened, my problem now is, do I want to read a book written by someone so obviously contemptuous of me, no matter what decade the writer lived and worked in? I think the answer is NO! I was truly enjoying the book up until location 2458-61, and had even gone so far as to call my sister and recommend them to her. I am truly trying to be a bigger person and but I cannot truly support people who do not respect me. I am deleting this book and the "Rosa Mundi and Other Stories" today. Life is hard enough and I shouldn't have to fell insulted by something I bring into my home for pleasure. Sorry Ethel, ya gotta go!
[EX A]: Negative

[EX Q]: T.H.White must have published at least three slightly different versions of this story.When I read the full Once And Future King book a few years ago, there was no Madame Mim episode, there was a buttery version of the fairy castle (Robin Hood) episode, there was an Archimedes/Wild Geese episode, and some other minor changes/additions.When I read a paperback Sword In The Stone twenty years ago, there was a much nicer non-buttery version of the FairyCastle/RobinHood episode, and I don't think the Giant Galapas episode was there, etc.Now I've just read the illustrated hardcover Sword In The Stone edition, and the FairyCastle/RobinHood episode is replaced by an Anthropophagi/RobinHood episode, Giant Galapas is there, and the Archimedes/WildGeese isn't (its been replaced by an Archimedes/Athena episode).Anyone else notice these differences and have an explanation for them?
