Thirty years ago when Putnam's Sons decided to publish Stranger in a Strange Land they had no idea of what they had in their hands. I don't know what they changed of Heinlein's original manuscript, but enough that they are now publishing the original uncut version. For you who have read the earlier version, this gives you a chance to judge which is the better. What a thrilling idea, to be able to read a great book just as the author meant it to be read.
This HC, from 1991, can be yours for only $3.50. Look for it in the science fiction section.
