The New York State Library is not the official repository of the wills of New York State residents. These records can usually be found in county courthouses. The court of probate in New York is the Surrogate's Court.
The New York State Library does have probate records such as calendars, abstracts, indexes and inventories of wills and administration papers. It also has some copies of actual wills in print form and microfilm.
