The Writing series is made up of the professional written works by Stine associated with sports model rocketry, non-fiction aeronautical writings, and science-fiction works under the pennames Lee Correy, George H. Shearer, and Gregory Hamilton Stone. When Stine used a penname for the work, it is noted alongside the folder title. The types of material that make up this series are galley proofs, typed manuscripts, photographs, illustrations, tear-sheets of magazine articles, notebooks, and correspondence. There are five subseries in this grouping: Subseries A. Book Manuscripts, 1950-1995; Subseries B. Short Works, 1951-1995; Subseries C. Notes, 1965-1971; Subseries D. Assorted Works, 1948-1971; Subseries E. Works by Other Authors, 1958-1994.

Subseries A. Book Manuscripts has been broken down into fiction and non-fiction writings, with files in each subseries arranged alphabetically by title. The fictional works include well-known titles like Rocket Man under the penname Lee Correy. Some folder titles may not be the published title for the novel and may also include other examples of working titles for the manuscript. Included in this subseries are typed manuscripts, correspondence, and photograph selections related to the work. Within the non-fiction grouping, there are many famous works by Stine, including the first manuscript of Handbook of Model Rocketry from 1961, and the sequential revisions and editions throughout the years until 1993. In addition to the Handbook of Model Rocketry there are manuscripts related to other books on model rocketry such as Model Rocketry Manual, which Stine began writing in 1970.

The Short Works subseries is also subdivided into fiction and non-fiction writings. The fiction subseries includes early examples of Stine’s science-fiction articles beginning in the 1950s. The non-fiction subseries includes articles on model rocketry for various hobby publications, most notably Model Rocketry Magazine and American Modeler Magazine where he was a content contributor beginning in the 1950s. The recurring columns “Countdown” and “Rocket Trails” were regularly featured in the American Modeler Magazine, and he had a recurring column in Model Rocketry Magazine titled “The Old Rocketeer.” These writings updated the sport rocketry community on current happenings, highlighted competitions, summarized new theories in model rocketry, and presented how-to designs. While the fiction short works are arranged alphabetically, the non-fiction works were filed in reverse chronological order following Stine’s original organization.

Subseries C. is a very small subseries made up of Stine’s three notebooks on model rocketry. One of them is titled the “Personal Idea Book from the department of Witchcraft and Sorcery.” The notes are accompanied by illustrations of the model rocket designs. They have been arranged in chronological order.

Subseries D. has various examples of works by Stine that run from book reviews, teacher’s guides, and very early play scripts like "The Battlements of Eternity" from 1948.

The last part of the series is a small subseries of manuscripts by other authors that relate to aeronautical research and model rockery, for example Gerald M. Gregorek’s "A Critical Examination of Model Rocket Drag for Use with Maximum Altitude Prediction Charts" and “Physical Reality” by Robert L. Carroll.
