Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

Michael R, to fill in one blank: The tall, ornate building on the far right is the former HQ of the forerunner of PNC Financial. It stood at NW corner of 5th & Wood and was torn down to build One PNC Plaza. Behind it, barely visible, is the former Farmers Bank Building, which was torn down---after a horrific 1960s renovation---for the new Lazarus department store. I am intrigued by the foreground of the photo. I am betting the photo was taken from the top of the Diamond Bank Building. You can see the shadows of letters in the photo. There is a pic of the rooftop letters on the Shorpy's web site.
I can see two buildings designed by D. H. Burnham & Co. of Chicago in this view: 1) Union Station (1898-1903), the hazy square block at the "end" of Liberty Avenue; and 2) the Oliver Building (1908-1910), seen here from the back as a 3-part structure with two deep light courts in the right-center background. Both are still standing. Other than the peculiar Keenan Building (at left, with the dome), I cannot identify the other tall buildings. Can anyone fill in the blanks?
Last time I ran the 'Burgh Marathon, we finished down Liberty to Point Park.Who knows the town well enough to tell us if any of these buildings are still there (many details of one's surroundings blur during miles 24 to 26.2)?
