Aftermath Club records span the dates 1895-2004, and comprise Administrative records, Financial and Legal Records, Club Activities, Yearbooks, Club History, and Artifacts.

Administrative Records span the period 1897-2004, and contain Articles of Incorporation (1904), incoming and outgoing correspondence (1948-1988) and minute books documenting the Club's meetings from 1899 until its disbandment in June 2003. Most are hand written and kept in bound volumes; however, in later decades the minutes are predominantly typed.  The first volume contains the Constitution and By-Laws of the Aftermath Reading Circle (the original name of the Aftermath Club), as well as the first  membership roll.  Later volumes include press reports of meetings, printed yearbooks of scheduled activities, and a small number of photographs. 

Financial and Legal Records contain legal material regarding the clubhouse, the treasurer's financial reports, and Member and Dues ledgers dated 1931-1997. The series also contains nine volumes of redeemed and unsold stock certificates sold by the Aftermath Club from 1904-1977.

Club Activities records include annual reports written by the club historian.  The first of these histories was written by Mrs. Helen Phillips, the first Aftermath Historian, whose report spans the period 1895 through 1907.  The annual histories, presented at the final meeting each year, begin in 1908 and continue through 2003 and include clippings, fliers, letters, and some photographs.  The series also includes newspaper clippings and press releases, scrapbooks covering the period from 1990-2003, and papers presented by members to the rest of the club.  These are listed as "Presentation Materials," and span the dates 1898-1986. 

The collection also contains Yearbooks spanning the period from 1898-2003 (with the exception of the yearbook from 1906-1907). Published by the organization, the yearbooks contain a general listing of annual officers, weekly meeting programs, and a listing of active members.  While the format of the yearbooks varied slightly with changes in the list of study topics and other events, and with the inclusion of the organization’s constitutions and by-laws, the practice of printing yearbooks continued until 2003.

The Club History series contains papers and an inventory written by Susan Fahey for the members of the Aftermath Club in 1994, as well as Fahey's Master's thesis, also presented in 1994.  This series also includes a local calendar printed in 2004, (celebrating Bellingham's Centennial) which features a page detailing the club's history.

Artifacts comprise the incorporated seal of the Aftermath Club and a hand-painted pin commemorating the centennial of the Club in 1986.
