[SOLD] If a book or article is old enough, it is out of copyright and Google may have scanned it and put it on the web. It seems some people assembled many old books and articles on certain topics, put them on CD and sold them for $10-$15 on eBay. Years ago I bought these four: Most computers don't even have a way to read CDs any more. But, if yours does, you might like them. I'll pass all four along, in the US only, for $9+$4 shipping. I am not going to list the contents. They have hundreds of old (mostly outdated, some in foreign languages) articles and books. PM me if you are interested.
