DRAWING comparisons to Edward Snowden, a graduate student from Kazakhstan named Alexandra Elbakyan is believed to be hiding out in Russia after illegally leaking millions of documents. While she didn’t reveal state secrets, she took a stand for the public’s right to know by providing free online access to just about every scientific paper ever published, on topics ranging from acoustics to zymology.

Her protest against scholarly journals’ paywalls has earned her rock-star status among advocates for open access, and has shined a light on how scientific findings that could inform personal and public policy decisions on matters as consequential as health care, economics and the environment are often prohibitively expensive to read and impossible to aggregate and datamine.

“Realistically only scientists at really big, well-funded universities in the developed world have full access to published research,” said Michael Eisen, a professor of genetics, genomics and development at the University of California, Berkeley, and a longtime champion of open access. “The current system slows science by slowing communication of work, slows it by limiting the number of people who can access information and quashes the ability to do the kind of data analysis” that is possible when articles aren’t “sitting on various siloed databases.”

Journal publishers collectively earned $10 billion last year, much of it from research libraries, which pay annual subscription fees ranging from $2,000 to $35,000 per title if they don’t buy subscriptions of bundled titles, which cost millions. The largest companies, like Elsevier, Taylor & Francis, Springer and Wiley, typically have profit margins of over 30 percent, which they say is justified because they are curators of research, selecting only the most worthy papers for publication. Moreover, they orchestrate the vetting, editing and archiving of articles.
