Why HP is not a NY Times Bestseller

[Alex]

Too bad, without that extra publicity nobody will know about the new book.

It's the same reason the Advice listing was created, because self help books were dominating the list so that nothing of interest outside that niche was showing up. It is also the same reason that a length cap was put in place for being on the list (no more books on the bestseller list for five years).

The NY Times bestseller list hasn't been about "truth and accuracy" for a very long time (also ignored is the fact that many major book outlets don't even show up in the system used to create the list or Christian lit would prominently dominate in a huge way).
