[3] Originally consisting of a single room in The Citadel Academy's campus at Marion Square from 1842, the Cadet Library continued to expand and evolve throughout the college's history.

The Daniel Library building was completed in 1960, and is situated on The Citadel's campus along the Avenue of Remembrance and next to Summerall Chapel.

The renovations cost $2.2 million and were financed entirely with private donations, with the lead gift coming from the Daniel Foundation of Alabama, founded by the namesakes of the Library.

Among other exhibits, the Museum features displays on cadet life in earlier years and a collection of class rings dating to 1895.

Elsewhere in the library are exhibits relating to author Pat Conroy and swords carried in active military service by alumni including Charles Courtenay Tew[6] and James B.
