the uc berkeley earth sciences & map library has some nice, mostly historical aerial photographs of the san francisco bay area. it's interesting to compare them aesthetically to google earth. look closely at the color image and you can see the freeway that collapsed in the east bay after the 1989 earthquake. enter the archive here.
