Extracted from The Big Think, Simon Oxenham tells “…The tale of how one researcher has made nearly every scientific paper ever published available for free to anyone, anywhere in the world.”

“On September 5th, 2011, Alexandra Elbakyan, a researcher from Kazakhstan, created Sci-Hub, a website that bypasses journal paywalls, illegally providing access to nearly every scientific paper ever published immediately to anyone who wants it. The website works in two stages, firstly by attempting to download a copy from the LibGen database of pirated content, which opened its doors to academic papers in 2012 and now contains over 48 million scientific papers. The ingenious part of the system is that if LibGen does not already have a copy of the paper, Sci-hub bypasses the journal paywall in real time by using access keys donated by academics lucky enough to study at institutions with an adequate range of subscriptions. This allows Sci-Hub to route the user straight to the paper through publishers such as JSTOR, Springer, Sage, and Elsevier. After delivering the paper to the user within seconds, Sci-Hub donates a copy of the paper to LibGen for good measure, where it will be stored forever, accessible by everyone and anyone.

This was a game changer. Before September 2011, there was no way for people to freely access paywalled research en masse; researchers like Elbakyan were out in the cold. Sci-Hub is the first website to offer this service and now makes the process as simple as the click of a single button.

As the number of papers in the LibGen database expands, the frequency with which Sci-Hub has to dip into publishers’ repositories falls and consequently the risk of Sci-Hub triggering its alarm bells becomes ever smaller. Elbakyan explains, “We have already downloaded most paywalled articles to the library … we have almost everything!” This may well be no exaggeration. Elsevier, one of the most prolific and controversial scientific publishers in the world, recently alleged in court that Sci-Hub is currently harvesting Elsevier content at a rate of thousands of papers per day. Elbakyan puts the number of papers downloaded from various publishers through Sci-Hub in the range of hundreds of thousands per day, delivered to a running total of over 19 million visitors.

The efficiency of the system is really quite astounding, working far better than the comparatively primitive modes of access given to researchers at top universities, tools that universities must fork out millions of pounds for every year. Users now don’t even have to visit the Sci-Hub website at all; instead, when faced with a journal paywall they can simply take the Sci-Hub URL and paste it into the address bar of a paywalled journal article immediately after the “.com” or “.org” part of the journal URL and before the remainder of the URL. When this happens, Sci-Hub automatically bypasses the paywall, taking the reader straight to a PDF without the user ever having to visit the Sci-Hub website itself.”
