New York State Library: Digital Collectionshttp://www.nysl.nysed.gov/scandocs/
Resources available: many New York State publications, both contemporary materials from 1995 to the present and selected publications from earlier years; some historical materials from the 18th through the early 20th century in many subject areas, including the Revolutionary War, the Civil War, Native American materials, New York State laws and natural history; and, along with books, primary source materials (e.g., letters, diaries and rare manuscripts, maps, music scores). Newer State documents are generally "born digital," while older items have been scanned from original copies located in the State Library. All material is made freely available online, usually as PDF documents.
