The Simon Hart Chronology represents summaries of notarial records relating to New Netherland located in the Municipal Archives of Amsterdam. In the 1650s the notaries of Amsterdam were directed, upon retirement or for other reasons, to deposit their protocols in the municipal archives for safekeeping. Simon Hart, during his tenure as chief archivist, spent his free time in the “Depot” of the archives, searching through the protocols. The for references to New Netherland. His findings were typed onto cards which were eventually microfilmed. In 2018, the NYSA had the cards digitized for use of researchers. The information on the cards contains anything that would have required sworn testimony before a notary, such as last wills and testaments, witness testimony, contracts, powers of attorney etc.  The link above takes you to a google drive where the cards may be downloaded.
