These folders document Hackman's preparation of articles for publication. They are mostly concerned with broad archival policy matters and other issues of profession-wide importance. Many of the articles appeared in the American Archivist, The Public Historian, and JANUS. There are also folders on book chapters, technical leaflets and magazine articles, e.g. State Government News, Empire State Report, which he authored, and folders on some presentations that did not result in a publication.

Some of the publication files contain drafts of presentations, especially keynote, plenary, and core sessions papers delivered at professional meetings, including the Society of American Archivists Annual Meetings. Folders often contain correspondence, feedback from other archivists, background materials, and working drafts.
