Worldwide Statistics: How Students and Educators Use Z-Library

Worldwide Statistics: How Students and Educators Use Z-Library

Apr 27, 2023

It's no secret that the most active users of our library are students and staff from various universities. We wanted to learn more about this and have collected statistics showing which educational institutions use Z-Library and how they use it. How did we separate one university user from another? For data collection and analysis, we decided to rely on the domain zone where users' email addresses are located. For example, an email like "*" allows us to assume with a high degree of confidence that this is an employee or student of the University of Toronto.

During the collection of statistics, we discovered that Z-Library is currently used by more than 600,000 students and teachers from over 30,000 educational institutions (universities, colleges, and schools) worldwide! These values, and the numbers in the graphs below are a low estimate since not all users give their university email addresses when registering. However, the obtained statistics should be relatively accurate. Also, due to the large number of users from China, we decided to combine the largest universities of this country into one line.

So, let's start with the general statistics. In which countries do university students and staff use Z-Library most actively? (We highlighted Taiwan due to the significant number of our users located there. There are no political reasons involved).

Then we collected statistics broken down by universities:

As you know, all books available in Z-Library are uploaded by users. Let's see which universities have made the most significant contribution to the library's replenishment:

Many universities also use Z-Library to compile collections of educational materials presented as Booklists.

Lastly, we would like to express special thanks to those who have financially supported our project!

It should be noted that when compiling statistics, we excluded all data related to the United States. This is because, at the request of the United States, two Russian citizens have been illegally arrested and are being held in custody by the FBI on suspicion of involvement in Z-Library. However, despite the pressure exerted by the FBI, we strive to continue our work and hope that an increasing number of universities will continue to use Z-Library in their educational activities!


Bad libraries build collections, good libraries build services, great libraries build communities
