How this list was made: I searched Barnes and Noble online for "Civil War." Sorted the list by "Bestselling." Removed the following items: novels and poems, books selling at deep discount (i.e., being liquidated), and topically irrelevant titles.
The place a book would have occupied if I had not made such list edits is shown in parenthesis after the title: "Title of Book (34)."
The overall "Barnes and Noble Sales Rank" is its ranking outside of the Civil War context. This is followed by my estimate of 2004 sales as per Ingram times six (as of 12/28/04).
The titles in the list link to Amazon, with which this site is affiliated. Amazon will not carry some books published by Barnes & Noble, so the first link in the list, which is a B&N title, should draw a blank. You might amuse yourself by clicking a link and comparing the B&N sales rank with the Amazon sales rank.
