Pittsburgh Picture of the Day
This is the Mezzanine level of the stacks section of the Carnegie Library of Pittsburgh, Main Library. There are eleven floors of stacks and the shelves are the entire support for this section of the building! The aisles inside each book stack (the shades of green you see on the right and the left) are made of glass while the main center aisle is marble. On this level, which is open to the public, you'll find books in the A-L sections of the Library of Congress (LC) classification system. Yes, they use LC instead of the more public library-popular Dewey Decimal system here and I'm lost without consulting a guide. Only three of the stacks are open to the public: third stack (which is level with the first floor of the library), fourth stack (which is called the Mezzanine because it's between the first and second floors of the library), and fifth stack (which is level with the second floor). 8th stack is only open to the public with a staff member and that stack is level with the third floor. The rest of the stacks (including 1st and 2nd stacks which are in the basement) hold serials, music folios, engineering standards and codes, government documents, and reference, circulating, and oversized Dewey Decimal system books (from before they switched to LC) and LC books.
Oh, and lots of old coal dust. Really.
