not sure what sort of documetary photography books you mean
like street photography, human condition ?
the americans by robert frank,
the works of margaret bouque white
and while it isnt in a book the oeuvre of colin corneau
architctural documentary work --
go to the habs project website and have them look
at as many HABS / HAER documentations as they can
have them look for the book jack boucher did ( he was the head of the habs project for decades )
as well as the images of jet lowe ( i thought he had a book i guess i was wrong )
christopher payne is in nyc and i think he has a book out regarding NYC "stuff"
as well as the complete works of atget
the bechers have a few good books out too
and these MIT planning library images on flickr by Nishan Bichajian
