The “History files” series is arranged into a large number of subseries. The first fifty-eight subseries are arranged by Park, alphabetically, beginning with Allen’s Lane Park and ending with Wooden Bridge Run.

The information in each of these Park subseries is organized in a uniform fashion. The material in each of the Park components, or “subseries” is first organized alphabetically by feature with any particular Park. For example, some primary subdivisions of “West Fairmount Park” subseries are “West Fairmount Park, Belmont Mansion;” “West Fairmount Park, Boelson House;” “West Fairmount Park, Chamounix Carriage House;” and “West Fairmount Park, Japanese House.”

At the next level of organization, beyond park feature, is subject matter. The order of the subject matter arrangement is as follows: The first subject is general historical background information. After the historical background is background information specific to the work of the Planning Preservation and Property Management Division, including capital project preservation documentation and maintenance records. Lastly, administrative information is found in the form of grant applications, Park “Friends Group” communications, and institutional designations.
