That way when I do a web search (ok, Google), I know if its an article that I can actually read, or one that I'll have to purchase.
Search will give true information about free, trial, paid already, or demanding pay for webpage entry.
I'm finding it extremely exasperating doing web research, and getting to articles that I have to pay for, while most of the info is out there free, and the paid articles are usually useless.-- pashute, Apr 05 2011 bone fide?-- pashute, Apr 06 2011 random, halfbakery
