I must say I have read about 10 of his novels (few of those are with Silverberg). Few days ago I went on wikipedia to see an article about his "I, Robot" book and the first sentence of the article describe the book as collection of nine homosexual English language science fiction short stories. At first I thought that someone is just goofing around and now the article is changed the word 'homosexual' is edited out. But article can still be seen in history of wikipedia. (sorry I can't give you the link the forum don't allow me because I have to little posts, but you can see it on wikipedia history under date 06:07, 6 March 2008)
So I made a little searching around and find out that novel "The Robots of Dawn" are 16th on amazon list of Best Gay Books.
So what does it means? Since I have not yet read those books I'm just wandering are they gay and if they are why is it suppressed by wikipedia? They don't even mention it actually no one mentions when they talk about Asimov's robot books.
