DDC has a role in new landmark Seattle public library building:

Even with its unusual shape, the standout feature of the library, at 1000 Fourth Avenue, (206) 386-4100, www.spl.org, may well be the Books Spiral, a gentle ramp that winds through four floors spanning the entire Dewey Decimal System and allowing a visitor to walk continuously from one subject area to another. The grand opening, scheduled for May 23, comes near the end of a civic makeover that has transformed Seattle in the last decade, with two stadiums, a new City Hall and downtown retail centers.
