...Guarding that "aha" moment - "when you read something and it literally takes your breath away," is honorable...NotHBPSpoiler
The Christian Science Monitor has a piece about the security measures surrounding HBP. They interview various booksellers and librarians about Scholastic's secrecy policies, and booksellers like Russ Lawrence, of Chapter One Books in Hamilton, Montana strongly support Scholastic and their reasons for secrecy.
Scholastic Inc., the book's US publisher, has once again gone to great lengths to make sure that nothing is leaked in advance. Store managers must sign affidavits that they will not release the book prematurely. Distribution centers keep the tomes in restricted areas, often watched by security guards. Scholastic won't reveal what goes into printing, distributing, and protecting the more than 16,000 tons of books. A company representative even declined to say how many reams of paper such an undertaking requires.
