Delighted to see these online. Years ago I laboriously copied those I could 
find in the Hillman Library, and I've shared some of them with a few of you. 
Invaluable to PRCo groupies.

Caveat: there are a lot of gaps in PRCo territory, where the lines were beyond 
the reach of the Pittsburgh city cartographers. But sheets were published 
entire, even in cases where they might include just a few square yards within 
the city limits.
