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.
