The Encyclopedia of New York is definitely the place to start, but as I recall there is a typo in either the date or the name of one of the tallest buildings in succession. Sorry I don't have my notes here to say which one and I think it is self-evident, but just keep an eye out for it. You should look at entries for each building and the entry on skyscrapers in general. You might also try contacting Carol Willis of Columbia who has started a Musuem of the Skyscraper. I don't know whether the museum has a phone number and I believe she adjuncts in the architecture school at Columbia. Nancy Robertson
