The paper investigates the "stat of the art" concerning the sources on the Second Vatican Council. The exposition is founded on the division operated by the authors of the History of Vatican II, directed by Giuseppe Alberigo and published in five volumes from 1995 to 2001. Following this model, the paper shows the three main groups of sources: conciliar documents and proceedings, collections of letters, diaries and others statements of the participants. Finally, the article proposes an exposition of the new researches on the catholic press and on the television during the years of the Council.
