The Hogg Papers consist primarily of class notebooks and photographs created by brothers Ronald V. and John G. Hogg. The class notebooks are for a variety of agriculture courses including agricultural economics, bee culture, crop production, farm accounts, hippology, and horticulture; science courses including anatomy, botany, chemistry, and zoology; as well as English, American government, library practice, and camp cooking. Of special note are a botany class taught by Helen Gilkey in 1918, recipes in the camp cooking notebook, and references to the current (at the time) war in Europe (World War I) in a military science course on war aims.

The certificates are for the membership in the Oregon Chapter of Alpha Zeta, the agriculture honor society, and a postcard to Ronald V. Hogg confirming his admission to Oregon Agricultural College in 1918. The directories consist of the 1921 and 1922 issues of the ,which lists all students and faculty, and a directory of all chapters of the Alpha Zeta fraternity issued in 1922.

The photographs consist of nitrate negatives depicting the Hogg family farm and the farm's award-winning pigs, campus buildings, a vacation to the coast, and an exhibit of Oregon agricultural products at an unidentified event (perhaps the Oregon State Fair). It is possible the photographs were made by Ronald Hogg for the photograph class he took in fall 1922.
