Science: Over the 6 months leading up to March, Sci-Hub served up 28 million documents. by John Bohannon
'More than 2.6 million download requests came from Iran, 3.4 million from India, and 4.4 million from China. The papers cover every scientific topic, from obscure physics experiments published decades ago to the latest breakthroughs in biotechnology. The publisher with the most requested Sci-Hub articles? It is Elsevier by a long shot—Sci-Hub provided half-a-million downloads of Elsevier papers in one recent week.
'These statistics are based on extensive server log data supplied by Alexandra Elbakyan, the neuroscientist who created Sci-Hub in 2011 as a 22-year-old graduate student in Kazakhstan. I asked her for the data because, in spite of the flurry of polarized opinion pieces, blog posts, and tweets about Sci-Hub and what effect it has on research and academic publishing, some of the most basic questions remain unanswered: Who are Sci-Hub’s users, where are they, and what are they reading?
'For someone denounced as a criminal by powerful corporations and scholarly societies, Elbakyan was surprisingly forthcoming and transparent. After establishing contact through an encrypted chat system, she worked with me over the course of several weeks to create a data set for public release: every download event over the 6-month period starting 1 September 2015, including the digital object identifier (DOI) for every paper.'
