This is "aged" non-fiction that deals with public policy, so it's hard to stay on top of bestseller lists with old stuff. That's one reason a big update is due this summer (see Oct. 1, 2011 for a preview). A lot can change in eleven (let alone "eleventy") years.
Once I connected and remembered how to use the Kindle (it's irritatingly clumsy to "type" a search term; I'd rather do it on a PC), the downloads went fast. My fist book is 183000 words and downloaded in less than a minute.
On Amazon, these Kindles sell for $3.99, which is much less than the price still asked for the hardcopy print. So Kindle may indeed be a way to keep older books in reasonable circulation.
No, it's not free -- it's realistic.
I guess I'll see $7.98 on my credit card for the downloads, and I'll get back a wee bit of royalty. Buy your own books!
Update: July 7
I got a silly email from Amazon asking how many stars I would give my own books. No, I won't rate them. I just bought them to test the process, inexpensively.
The Barnes and Noble Nook price seems to be $3.48.
Update: June 2, 2015
The Kindle versions of the first two books are no longer available. I am trying to find out why. The third book is available by Kindle.
Update: June 9, 2015
The first two books have been restored to Kindle. Still working on Nook.
