The sale of Hitler's "Mein Kampf" is banned in Germany.

According to an Amazon.com report at last month's Frankfurt Book Fair, "Mein Kampf" was its second most popular book sold to German customers.

German publishing giant Bertelsmann recently asked barnesandnoble.com to stop delivering the book to customers in Germany. Bertelsmann has a 40 percent stake in barnesandnoble.com.
