The White House moved Friday to make nearly all federally funded research freely available to the public, the latest advance in a long-running battle over access to research that exploded into view last month after the suicide of free-information activist Aaron Swartz.

In a memo, White House science adviser John Holdren directed agency leaders to develop rules for releasing federally backed research within a year of publication in scientific or technical journals.

"These policies will accelerate scientific breakthroughs and innovation, promote entrepreneurship, and enhance economic growth and job creation," Holdren wrote.
