This makes perfect sense, since NIH funding originally comes from tax dollars… so why would the public have to pay again to read an article? Of course, generally, a very small percentage of the public would actually be interested in reading these articles, but this is a separate issue.

While exciting, I think this new law introduces a few questions. For example, how will this law be enforced and/or monitored? i.e. who will determine/verify whether the research was funded through NIH money or not. Also, how will this new law affect the bottom line for journals and publishers?

I think it will be interesting to observe as the implications of this new law unfold. However, it still stands that this new law is one step closer to bridging the gap between Pub-Med and the general public.
