²Each sheet regarding the projects funded under the FP6 and FP7 is available on the website of the CORDIS (Community Research and Development Information Service) and contains information about the single organizations participating in the projects. This information includes the address of the organization, the administrative contact and their telephone number. The address of the public national research centers (e.g. the Consiglio Nazionale delle Ricerche – National Research Council) refers always to the central headquarters in Rome (Lazio), even though the administrative contacts and their related telephone numbers refer to the person and the separate branch actually involved. The risk to overestimate the number of participations of Lazio was prevented by reconstructing the branch actually involved in the projects by means of a thorough search on Google based on the names of the administrative contacts and their related telephone numbers.
