The American Book Company building, 330 East Cermak Road.

Being rehabbed as part of the Marriott Marquis Chicago in the Prairie District of the South Loop, the American Book Company building is being re-purposed as meeting rooms, office space, and retail.

Added to the National Register of Historic Places in 1998, the American Book Company building, designed by architect Nelson Max Dunning, was on the endangered list as recently as 2008, when a proposal for the block on which it’s located called for its demolition. It was then designated a Chicago Landmark in 2009.

Speaking of 330 East Cermak Road, Crain’s Chicago reported Thursday that a new data center is coming to this address, and would be situated directly behind the American Book Company building, just north on Calumet Avenue.
