The majority of the collection is made up of miscellaneous subject files, which follow Dr. Rosen's detailed research, colleagues, and projects. In addition to the subject files, four series of special subject files, denoting those of particular importance, have been created for subjects containing multiple files.

The collection also contains files on the publications of Dr. Rosen, in addition to a number of books either written or contributed to by Rosen.

Four of the cassettes in the Audio Visual Materials Series record interviews with survivors of suicide attempts from the Golden Gate Bridge. One film reel, Discussion with Dr. Carl Jung, is in a degraded condition and stored in the film vault.

As Dr. Rosen focused most of his work on Analytical or Jungian Psychology, the majority of his collection is dedicated to his research, publications, and lectures given on the subject.

This collection consists of one notebook (housed in a phase box), measuring approximately 10 x 8 inches, containing 49 leaves of machine ruled paper, in cloth over cardboard covers, which was manufactured with two-hole punched metal fasteners.

The front cover design shows: at the top "…A. & M. COLLEGE…, COLLEGE STATION, TEXAS"; in the center, a black and white picture depicting the Old Main building on the Texas A & M College campus, measuring 4.5 x 4 inches; below picture, "Department of" with a ruled space filled in by hand with ink the word "Horticulture," and "Name" with a ruled space filled in by hand in ink with the name "Jess Easterwood."; at center bottom, "PUBLISHED BY, W. M. WELCH MFG. COMPANY, 100 LAKE ST., CHICAGO, WELCH'S PATENT AUTOMATIC FASTENER." The name "EASTERWOOD" and other initials, etc. are scrawled in ink or pencil on the front cover as well.

Most of the notebook's leaves are filled in on the recto page only with class notes written by hand in either pencil or ink, labeled as taken from lectures. A few pages are filled with scrawled names and phrases, repeated over and over, the phrases usually in some way related to the lecture notes, but often just variations on Easterwood's name or initials.

One exception found on leaf 19 is the beginnings of a draft letter, dated January 25, [19]08, to his father, noting that Easterwood has been recently ill for a "protracted" period of time. Lecture notes in roughly the first half of the notebook pertain to Animal Husbandry [l. 1-14; l. 15-18 & 20 are blank], especially causes, symptoms, and treatment of conditions such as colic, heaves, constipation, dysentery, catarrh of stomach and bowels in livestock, while the latter half are concerned with a class labeled "Horticulture 4" [l. 21-49; the top half of l. 45 is torn out], particularly the cultivating of fruit trees and the marketing of their produce.

Aside from presenting an interesting taste of curriculum offerings at Texas Agricultural and Mechanical College in the early twentieth century, some of the notebook's scrawled asides give a quite colorful glimpse into the mind of a restless and enterprising cadet straying from the lecture in progress.

This collection consists of one "ATM Dave South Bobblehead Collectible Presented by AARP Texas", unopened and in the original box.
