Here is a book I have not read except for the excerpt in the link. "It Was Never About the Babe", subtitled "The Red Sox, Racism, Mismanagement and the Curse of the Bambino", is an attempt to see the history of the Red Sox as not the product of mystical powers but the product of deeply embedded racism.
A key article in debunking the curse is Glenn Stout's "A 'Curse' Born of Hate."
Leigh Montville's "The Big Bam" partially counters some of the issues raised by Stout. You can check out the whole mess on the 'Curse of the Bambino' wikipedia page.
