Jenks' map collection includes draft materials related to producing scholarly papers and presentations, atlases, maps, government publications, and other materials related to Jenks' cartographic research and work. It includes typescripts, proofs, reproductions of artwork, charts, figures, photographic positives and negatives, and other related materials.

Topics in the collection include but are not limited to statistical mapping, human and other populations mapping in Kansas and elsewhere in the United States and the world, three dimensional (3-D) mapping, agriculture and farming, map production, the use of computers in map production, etc. Some projects were completed on behalf of the Kansas government; some were completed with professional organizations and other associations with which Jenks was associated.

The collection is chronologically arranged by entries found on Jenks' curriculum vitae and physically organized by size of material; materials related to specific projects may therefore be found in multiple locations. A "Related Materials" note associated with individual folders indicate for which publication these draft materials were made. Jenks' curriculum vitae is included in the collection, making it possible to trace the development of his research activities chronologically.
