The Cybermetrics Lab is a research group of the Spanish National Research Council (CSIC). The organization is responsible for editing the Webometrics Ranking of World Universities. Currently more than 48,000 web domains of academic and research organizations are analyzed and are ranked according to their web presence and link visibility.
The Cybermetrics Lab started to design and compile web indicators in the mid 1990s, editing the first CSIC electronic journal, Cybermetrics, in 1996. Originally part of the National Documentation Center (IEDCYT, now extinct), the group is now located in the new facilities of the CSIC for the Humanities and Social Sciences in Madrid. The head of the group is Isidro F. Aguillo.
Major contributions of the group include the analysis of academic world and regional webpages, the discovery of a digital divide between North American and European top universities, and the development of new statistics for Open Access repositories.
