On this page you can examine in detail the bibliometric maps presented in the paper A comparison of two techniques for bibliometric mapping: Multidimensional scaling and VOS by Nees Jan van Eck, Ludo Waltman, Rommert Dekker, and Jan van den Berg (paper, preprint). Click on one of the maps shown below to open the map using the VOSviewer software. In order to run the VOSviewer software, version 6 of Java needs to be installed on your system. The data sets based on which the maps were constructed can be downloaded here. In case of questions, please feel free to contact Nees Jan van Eck.
