The Administrative Files series documents the founding and operations of the WPFC, including minutes of the Biennial meetings and Executive Committee meetings, press releases, annual reports (entitled "What We Did"), and correspondence, notably letters in protest of violations of freedom of the press and "fan mail" from individuals appreciative of the efforts of the WPFC. The series also contains copies of WPFC publications, including handbooks for journalists, reports, working papers, and lecture series, as well as publicity pamphlets for the WPFC and WPFC histories, declarations of free press, and amicae briefs. Also included are recordings of television appearances by WPFC members and of conferences, and materials related to International Press Freedom Day, begun in 1991 by UNESCO.

The Projects series documents several projects that the WPFC was involved in, including code words on phrases used to mask censorship practices in the post Cold-War era, the Coordinating Committee of Free Press Organizations and their Fund Against Censorship grants program, the Eastern European Aid Project, and the WPFC's media assistance program. The records predominantly include applications, meeting minutes, reports, and statements, as well as correspondence and related articles. The series also includes files of project proposals with related correspondence on if the proposal was accepted and background materials on the projects.
