The purpose of this article is to present the opportunities provided for researchers and academics by social networking websites in the context of their professional work. Moreover, the paper discusses the level of penetration of social websites by Polish academics on the example of Nicolaus Copernicus University (NCU) researchers. The results indicate that the level of presence of Polish academics on the academic social networking sites is small. Also, noticeable are the differences between the representatives of various areas of science. The author reflects on the reasons for such poor presence of Polish academics in the academic cyberspace.
