In reading New York Archives, a quarterly publication from the New York State Archives, I discovered a recent article about the collaboration of these two agencies. Recently it was agreed to post selected genealogical resources from the State Archives and Library along with some local government repositories. You can access the site via the State Archives' web page (www.archives.nysed.gov), create an account by using their email addresses and then search records from participating institutions.
NY State Census, 1915 and 1925
NY Census of Inmates in Almhouses, 1830 and 1920
NY Marriages, 1600-1784
NY Civil War Muster Roll Abstracts, 1861- 1900
For a full list, read the Summer issue, Volume 12 #1, page 5-6.
