The New York Criminal History and Your Own Copy
In New York the public route to a statewide criminal record is the court system's own search: the Office of Court Administration sells a statewide search of criminal court records by name and date of birth, at $95 a search. It covers cases that reached a court, not arrests that never did. The search is on the New York State Office of Court Administration site.
To see your own record, the route is a fingerprint-based Record Review through the Division of Criminal Justice Services. The state page SearchSystems verified for it is at criminaljustice.ny.gov/ojis/recordreview.htm.
