There are two ways to obtain a historical New York City criminal
record, provided that the documents are still existing.
The majority of surviving pre-1966 criminal records (mainly
represented by court documents) is kept by the New York City Municipal
New York City Department of Records & Information Services
31 Chambers Street, Room 103
New York, NY, 10007
The Criminal Court of New York City also keeps a number of historical
criminal records, although most files have been transferred to the
Records Room of the Criminal Court of New York City
150 William Street
New York, NY 10038
I hope that this will be helpful!
