"Disclosure: All of the links in the following lists are Amazon affiliate links. If you're opposed to me making a few cents off this blog, but you're interested in any of these books, they're easy enough to find by searching Google for the individual titles."

The author is honest enough to inform you about it.

I find Amazon affiliate links (especially text-based links) to be perhaps the least offensive form of advertising revenue on the web.

I expect just about anyone linking a list of books on Amazon to be using affiliate links.

You could always try this greasemonkey script which always substitutes your own Amazon affiliate id so you can sponsor yourself.

Which directly breaks the Amazon Associates TOS and would allow Amazon to not pay you and delete your account.
