It sounds as if PLoS is launching elitist journals, just like Science, Nature, Cell, and the New England Journal of Medicine. Why?
As things stand, open access journals are generally viewed as fairly small fish in the publishing pond, and we want to create a few bigger, more noticeable fish. Now that PLoS Biology and PLoS Medicine have gained international recognition, PLoS has begun the process of launching—and working with others to launch—diverse open access journals. In this way, we hope that open access journals will become the venue of choice for research publications.
