According to a blogger for the LA Times, EM Forster's Maurice is either ranked or not, depending on which edition you look for. (The Penguin Classics edition is ranked, but the WW Norton is not. Both were 2005 editions.) What possible "serious, intentional policy" would account for that?

On the other hand, I just tried searching for "em forster maurice" under "Books" right now on Amazon, and the first hit was the WW Norton edition. No other editions were shown, but the next four things listed were:

• Who's a Pretty Boy, Then?: One Hundred and Fifty Years of Gay Life in Pictures by James Gardiner
• Queer Facts: The Greatest Gay and Lesbian Trivia Book Ever by Michelle Baker and Stephen Tropiano
• National Healths: Gender, Sexuality and Health in a Cross-Cultural Context (UCL) by Worton & Wilson
• Gay & Lesbian London (Time Out) by Paul Burston.
