A user-friendly method for generating overlay maps

We follow the method introduced in Rafols & Meyer (forthcoming) to create the overlay map on the basis of a global map of science (Leydesdorff & Rafols, 2009). The steps described below rely on access to the Web of Science and the files available in our mapping kit (also available at http://idr.gatech.edu/overlaytoolkit). The objective is to obtain the set of SCs for a given set of articles; provide this to network software (we describe for Pajek); and output as overlay information to add to a suitable basemap.
