History of CLP – Main

CLP – Main was Andrew Carnegie’s original library gift to the City of Pittsburgh, and it shared space with the Carnegie Institute’s museum. It was dedicated on November 5, 1895, in the Music Hall by Mr. Carnegie. The building underwent a series of updates to become the space it is today, but it retains its classic charm and much of its original architecture.

The original 1895 twin towers flanking the Music Hall were removed when the building was renovated in 1907, and the Museum was provided with its own independent space facing Forbes Avenue. At that time, CLP – Main’s entry lobby was redesigned to incorporate two side staircases of Tennessee Marble. The original staircase from the Lending Department to the Reference Department was removed. An 11-story book stack was built to replace the original iron stacks, which were situated at the rear of the First Floor Lending Department and the Second Floor Reference Room (each floor had three stacks). An electronic book conveyer system was included in the stacks. A Special Collections Room was designated for rare and unique materials in 1985. Public access to the online catalog (CAROLINE) was provided in 1988, and public access to the internet throughout CLP – Main was provided with the completion of the renovation of the Second Floor in 1995. Most recently, the New and Featured Department and the Teenspace were fully renovated in 2004 to create a one-stop browsing collection for new fiction and nonfiction.

CLP – Main welcomes all ages of readers, researchers and visitors. For help, just ask a librarian.
