Drafts and manuscripts of articles by Gooden include "Report of Physical Properties of Pesticides" and "Optical Crystallographic Properties of DDT." Research files contain notes, graphs, charts, and articles with labels like "Viscosity," "Zinc Arsenate," "Sodium Arsenite," and "Rotenone." This collection also contains electron microscope micrographs, patents and patent applications by Gooden, and hundreds of 3 x 5" x-ray diffraction data cards published by the Joint Committee on Chemical Analysis by X-Ray Diffraction Methods. These x-ray diffraction cards contain notes, calculations, and authors and their publications. Also included in this collection are glass slides, photos and negatives of electron microscope images, approximately a thousand 3 x 4" cards of chemical compounds and other notes, and materials from the annual meetings of the Electron Microscopy Society of America from 1949 to 1966.
