These are the household records of the Papal and Cardinal households. Although there are 432 in the library, according to the inventory produced by Morello in 1973, only one has been digitized, and it is a scan from microfilm. It covers the reigns of Julius III (1550-1555) to Pius IX (1846-1878), though there are several gaps.
