[Air-l] Computer self help press

[Peter T.]

I wonder if there are studies into the computer press explosion? I would 
really like long term book sales figures or production figures.

I have not been able to find much about it or any idea of the size of this 
exploded production of books.

In particular dummies and idiots guides interest me but there are numerous 
other presses out there.
