The Seattle Central Library is the flagship of the Seattle Public Library System. It is a famous deconstructive building located in the city center, a building consisting of 11 floors (56 meters high) of glass and steel. The library opened to the public on May 24, 2004. The 34,000 square metre public library houses about 1.45 million books and other materials, including more than 400 computers, and has an underground public parking lot. The first year of use exceeds 2 million people. The library has a distinctive and prominent appearance, forming several discrete "floating platforms" that are like being placed in a large spider web.
