The case for open access to scientific research is beautifully made by Peter Suber in the current SPARC Open Access Newsletter. In linking (which I’ve just done) I follow Glyn Moody. I will follow Glyn also in quoting Peter (although I won’t duplicate his quote).
When publishers argue that there are no access problems… that’s mistaken; there are deep and serious access problems; publishers who really don’t know this should should talk more to the libraries who subscribe to their journals, and even more to the libraries who don’t.
