In 1690, Cardinal Ciampini proposed the establishment of a seminar or commission of ten or twelve scholars, selected from different countries, who should be charged with the task of examining the books issued from the different publishing centres and of making reports upon which could be based the selections of the Congregation of the Index. He proposed to bequeath to such a seminar his library and a capital sufficient to secure for each member an annual payment of one hundred scudi. The foundation never, however, came into existence. At the time of Benedict XIV, Cardinal Querini submitted a plea for the better organisation of the Congregation and offered an endowment to be utilised for the printing of the censorship opinions, but the offer appears not to have been taken advantage of. In 1622, Gregory XV instituted the _Congregatio de Propaganda Fide_, and to this body was confided the task of examining, and when necessary of prohibiting, books in oriental and other “exotic” tongues. In 1674, Clement X issued a brief prohibiting the printing, “even by Jesuits or other Orders,” of any works relating to the missions except with the authority of the Congregation. The penalty was cancellation of the edition and excommunication of those responsible for its production. After 1610, the edicts of the _Magister_ prohibiting individual books are infrequent. In 1690, we have an example of such an edict in the case of a treatise on the Immaculate Conception by the Jesuit Saliceti, which was printed in Rome with the censored passages duly cancelled in the text. It continued, however, to be the practice for each _Magister_, in taking office, to issue a general edict setting forth the regulations controlling the production of books. One of the most important of these required the comparison page by page, by examiners appointed by the censor, of the text of the book as printed with that of the manuscript which had been approved (and possibly corrected). Until this comparison had been made, no copies of the edition could be offered for sale.
