On another note, I found all my old prints last night. There were many more views of the railroad yards that I've forgotten about. Most date to 1977, a few from 1976, and a very few from 1978. (By 1978, I was moving forward with the rephotographic project.) It will be a difficult decision to choose for the book. Many of these newly-discovered photos are rather illustrative of the yards, showing warehouses, trucks, the "Q," and other features of a diverse industrial area.
I also purchased "New York Changing," a play on the title of a book from the late 30's, "Changing New York," by Berenice Abbott, one of my favorite photographers. She photographed the city in about 1938, including the outer boroughs, and a contemporary photographer rephotographed many of her sites in the late 90's and early 2000's. He was fortunate enough to be able to use one of her 8x10 view cameras! Lovely, wonderful prints with great descriptions. Here's what stood out: building are tilted (!), he worked over a period of time, instead of just one year (as we are--2009-2012), and his affection for the city is obvious. That's the most important thing. I still feel great affection for Denver. Despite the parking lots of 1978.
