If you ever want to nerd out for several hours looking for images of washing machines or women beating their laundry on rocks by the river may I recommend the outstanding image collection at the mid-manhattan branch of the New York Public Library. The have a picture of anything and everything you could possibly want, friendly staff, and! (get this) you can check actual photographs out of the library and take them home for your very own.
P.S. I'm deep into procrastination today so there will be more pointless posts to come!( I know you are all ecstatic).
