The publishing dinosaurs, predictably, are predicting that dire things will happen if the U.S. enacts strong public access legislation.
The simple fact is that in the day of the Internet, open access publication is a very great deal more efficient and effective than what was possible with print. One online copy is readily available to anyone, anywhere; plus with full libre open access, allowing for re-use, it is possible to use data mining techniques to much more rapidly advance research.
If the arguments that publishers have invested in this system make sense, here is a thought: why doesn't the U.S. enact a law protecting manufacturers of outmoded lab equipment? These people have invested in technology, products, and services, and every time a better technology comes along, they need to come up with new and better technology, or go the way of the dinosaurs. If the arguments of the publishing community make sense, so do this.
