Thanks for posting about these.   They sound very interesting.

librarian,

Pardon me for asking this but I like to better understand the
websites I read.  You post links from each book to amazon.com.
Would you be willing to tell us how much Amazon pays you when a
person clicks your link and when a person who clicks also buys?

I'm not criticizing you for trying to make money selling books on
the Internet, and I don't regard your posting as an off-topic
post purely for commercial gain.  I have no problem with your
doing it.  Creating book lists on specific topics is a kind of
service to people.  However it is possible that not every viewer
of the site realizes that this is a commercial enterprise.

Thanks.
