There are hundreds of magazines, newsletters, newspapers, and books available from various places on the Internet. Any of the major search engines will yield results with these key words. If you get too many hits or if you want to narrow the scope of your search, try adding key words for the subject material you're looking for.

Likewise, you will have to convert HTML into text before you can upload it to Road Runner.
