Something I found a few days ago, I believe it hasn't been posted here.
//www.theatlantic.com/infocus/2012/04/historic-photos-from-the-nyc-municipal-archives/100286/ The New York City Municipal Archives just released a database of over 870,000 photos from its collection of more than 2.2 million images of New York throughout the 20th century. Their subjects include daily life, construction, crime, city business, aerial photographs, and more.
oh wow.... I just was paging through very quickly and just as quickly realized that this deserves a much more thorough look. The crime scene photos and the horse drawn street sweeper, the bridge photos, and the sheep in central park make it so that I have to peruse these more carefully tomorrow.
