But since the Public Library of Science, which was started by a group of prominent scientists, began publishing last year, this new model has been gaining attention and currency within academia. More than money and success is at stake. Free and widespread distribution of new research has the potential to redefine the way scientific and intellectual developments are recorded, circulated and preserved for years to come.”
