Introitus et Exitus Cameræ Apostolicæ (Latin: What Comes In and What Goes Out of the Apostolic Camera) is a six-hundred-and-six-volume financial record of the Apostolic Camera of the Holy See, from 1279 to 1524, located in the Vatican Secret Archives. The volumes span the reigns of thirty-two popes from Pope Nicholas III to Pope Clement VII. The volumes relating to the Avignon Popes (1305—1387) as well as the following antipopes were moved from Comtat Venaissin to the Secret Archives in 1783.
