I agree that this book should be preserved.  First because of the obvious fact that it was written by a woman.  Second be it is thought to be the first full novel written.  While the feminist side of me wants to argue that women are better than men and that men are the ones who really approach sex in much the same way as the character, I will not do that.  I found one of the most interesting aspects (to me) to be not just that it was written by a woman but that a woman wrote a book with such content at a time like that.  The author achieved, rather well I think, the task of writing as the character not as an author creating a character.  Please keep in mind the extent of my knowledge regarding this book stems from this time capsule.
