The Eleazer Everett orderly book is comprised of 66 pages of Revolutionary War orders, kept by an American soldier stationed at West Point, and 42 pages of hand-copied vocal music. The military entries date from July 2-8, August 15-25, and September 26-October 10, 1780, and contain general orders, garrison orders, and marching orders. Benedict Arnold's treason and the trial and execution of John André are mentioned in the orderly book.
Orders include specific instructions for the troops (rations of food and liquor, bathing requirements, etc) as well as orders to the officers concerning conduct: "The Major Generals to wear a blue coat with Buff under Cloaths, two epilates with two Stars on Each, a black & white Feather in the Hat..." (July 3, 1780). The volume also contains garrison orders issued by Major General Robert Howe, and extracts of general orders issued from Washington's headquarters, with mentions of other generals such as Jedediah Huntington and British General Henry Clinton.

In addition to the military orders, the volume contains 14 songs (42 pages) for four voices.

Lyric content is primarily religious in nature.
