from Google translate:<p>Today is September 5th - the birthday of the Sci-Hub project and the project is already 10 years old.<p>In honor of such a round date, two million new articles have been added to the server today, specifically 2,337,229.<p>What is inside?<p>Most of all new documents are from Elsevier publishing house - about half a million. Springer is in second place with three hundred thousand articles, Wiley is slightly behind him. In principle, nothing surprising, these are the largest publishers today. But in general, there are more than a hundred different publishing houses.<p>Elsevier BV 508,566

Li 28,550
Zhang 28,127
Liu 21,770

Xu 8,833<p>And what about Russian surnames? The Ivanovs published only 400 articles, with 266 articles being for men and 134 for women. With the Petrovs, the picture is similar: 96 articles were published by men and 68 by women. According to statistics, Smirnov and Popov are among the most common Russian surnames, everything is exactly the same here: with the surname Smirnov 96 publications, with the surname Smirnov 44, with the surname Popov 139 publications, with the surname Popova 54.<p>Such statistics may indicate discrimination against women in our science. It is not possible to verify whether it exists in foreign science, since foreign surnames do not contain gender characteristics.<p>What are the research topics? To determine the topic of the article, I used the Scopus database, which lists the topics of each journal. In general, the base is, of course, strange, the principle of classification of sciences is not very clear. But in general, it turns out that medicine is leading in terms of the number of articles:<p>398,548 Medicine
