The Salt Lake City Public Library system's main branch building is an architecturally unique structure in Salt Lake City, Utah. It is located at 210 East, 400 South, across from the Salt Lake City and County Building and Washington Square. History The Salt Lake City Public Library was originally housed in the Salt Lake City and County Building in 1898. Thanks to a donation of land and money by a John Quackenbos Packard in 1900, a new library was built in downtown Salt Lake City; the building is now listed on the National Register of Historic Places. This building remained in use until the library outgrew it by the early 1960s. The city library was then moved to a new home across from the City and County Building at the intersection of 500 South and 200 East. The groundbreaking ceremony was held on December 28, 1962, and the building was dedicated on October 30, 1964. In 1965, the old library was renovated into the Hansen Planetarium, funded by a donation of $400,000 from Beatrice M. Hansen. 1994 hostage incident On March 7, 1994, a gunman took several hostages in a conference room on the second floor of the old main branch building. The library was evacuated and SWAT teams were called in during a six-hour siege, which ended in the death of the gunman and the freeing of the hostages. Move to the current location After celebrating the library's 100th anniversary in early 1998, an $84 million library bond was approved to relocate the library in a new building, north half a block, to its current location. The firm Moshe Safdie and Associates partnered with a local architecture firm, VCBO Architecture, to design the building, which opened to the public on February 8, 2003. The former building in Library Square houses The Leonardo, a museum of science, technology and creativity. On September 15, 2006, a small bomb exploded in the third floor of the main building. No one was hurt, and the damage sustained by the building was a broken window. Eastbound traffic on the streets of 400 South and 200 East was closed as 400 people were forced to evacuate. Suicides and attempted suicides There have been several public suicides at the library since its relocation. In April 2008, a woman jumped from the third floor balcony inside the library and died. In July 2005, a woman jumped from
