From here, you can search the NASA ADS database for papers written by a specific author. The query will run by default against all refereed papers in the Astronomy database but optionally the Physics database can be included.
After the query is completed, you can choose to display statistical data on the author or to plot various relevant quantities using the corresponding buttons. The statistical data allow also one to compare the performance of the author with the ones among Italian assistant professors ("Ricercatori"), associate professors ("Professori Associati"), and full professors ("Professori Ordinari"). More details on the scheme used to calculate the various quantities are available on a dedicated page.
