In the scuffles over copyright policies on scholarly articles, what is the academic author to do? First, inform yourself. Find and read the copyright policy of the journals (or refereed conferences) to which you submit the articles describing research results. Find out the subscription price (dead-tree-edition or online) that the publisher charges individuals and institutions, and compare with the norms in your fields and others. Decide for yourself whether your publisher is unduly limiting the spread of ideas, or charging such prices that the effect is the same.
Remember what Thomas Jefferson wrote in 1813:
That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property.
