Commissioned in 1990 and completed in 1995, it is one of the largest libraries in the United States and receives more than one million visitors each year.
The $430,000 project had been funded by Scottish-American philanthropist Andrew Carnegie and would serve as the main branch library in Denver for over forty years.
However, due to a rapidly increasing population, a bigger structure would be needed to house Denver's growing collection of books.
Meetings took place inside of the General Reference room, which is located on the first floor of the library.
The Summit convened in the library's Vida Ellison gallery on the seventh floor for lunch.
