The fonds is divided into series, following the provenance and arrangement of the depositor as much as possible. Among the principal series are: President's binders or files, Secretary's binders or files, CHLA/ABSC special reports, and CHLA/ABSC publications. Within the series are found sub-series, i.e. President's binder, correspondence. The organization of the binders revolves around the Board Meetings, which occur three times a year, in June, October and February. At this time, reports are presented and decisions acted upon. Addenda to the Board Minutes frequently exceed 10 items. The fiscal year is from June 1 to May 31.
