The Haverford Athenaeum records span the years 1858 to 1888, up until the eventual merging of the Haverford Athenaeum with the Everett Society in 1889. The collection includes four series; first, the Constitution, By-Laws, and Official Minutes series. This series contains the original constitution, whose articles outline rules regarding future modification of the constitution, the duties and titles of the officers, the process for election and resignation of officers, the requirements for election to office and for membership, and more. The by-laws similarly outline the organisation's requirements, protocol, and disciplinary policies for failure of duty. The Haverford Athenaeum's minutes are included in all four volumes of this series, and are generally logistical in subject matter, containing information such as the the attendance record, the topics of essays read or subjects debated, and accounts of any change in officers or members. These official minutes are recorded by the Haverford Athenaeum's secretary. The second series contains the Treasurer's Accounts. These two volumes vary in detail, with the second (1876-1888) including more thorough information, but both volumes record the dates, names, and amounts of money received or spent. The third series includes the Haverford Athenaeum's private literary journal, The Gem. Series three contains all volumes of the handwritten literary journal, excepting Vol. 5 (1861). The Gem includes original essays contributed by student members. The fourth and final Miscellaneous series contains publications by the Haverford Athenaeum regarding society events, including the script of an address on President Lincoln.
