My post were deleted for the reason of "spam". I have a puzzle. What is the difinition of "spam"? Is it for commercial or opinion? Post in some other sites with same thing will be spam? What about I post it first in here? Different libraries and book store have same books for sale. Would you say it's a "spam" that Hilary's book "living history'' are everywhere in store? Internet site like a book store serve for certain people. If they didn't read it here, they may miss it because people not like you search all the way if this article is posted in other sites.

Re: "Yes, you did - on about 30 different forums. All you do is spam various
boards with the exact same text. Learn how to quote and post original
thoughts, or please do not bother posting at all"

This is a discussion forum, not a bookstore. Cross-posting something gives the impression that you are just trolling and have no real desire to engage anyone in discussion.
