A while back, in order to find books about atheism on Amazon, you could click through the following links:
Amazon –> Books –> Religion & Spirituality –> Spirituality –> Atheism
(You could argue that atheism doesn’t belong in a Spirituality section — and you’d be right — but that’s another debate.)
Now, the atheism section is gone.
The new pathway looks like this:
Amazon –> Books –> Religion & Spirituality –> Spirituality
Not only is “atheism” gone, the only subcategory under Spirituality is “Personal Transformation.”
So instead of Richard Dawkins‘ The God Delusion being (perhaps) #1 in “Atheism,” it’s #63 in “Spirituality.”

Why is this an issue? Simple. It makes it more difficult to find books about atheism in one location on the site.
I never knew why it was so hard to put an “Atheism” section along with the other Religion subcategories before… but to get rid of it altogether? I don’t understand why. Are there not enough books to justify it? I would find that hard to believe… (Hell, there used to be a “Top 100 in Atheism.”)
I asked Amazon about it via their livechat function. Here’s how that went down:

In summary:
“… This section is no longer available.”
No word yet on when they’re “taking care” of this.
