The New - York Historical Society has an online database of the vast collection, called emuseum. N-YHS houses over 60,000 objects and works of art that may be viewed online through emuseum. Three million manuscripts, photographs, prints, maps and books complement these art and artifact collections and are accessible at Bobcat. Also accessible online is the Gilder Lehrman Collection, on deposit at the Society. This is a great digitization effort to make the collection more accessible to the general public as well as serious scholarly researchers. After working at the Society and using the database everyday, I find it useful to an extent. Many of the objects contain no image and little information. Also some of the entries had errors and often things were hard to find even when you had all the information, due to lack of cross listing and keywords.
