This subseries is arranged as follows: first administrative reports of the director, leaders, and district agents in chronological order followed by departmental reports arranged alphabetically and chronologically within individual files. These are followed by county agent statistical and narrative reports and then county agent Plan of Work reports. All of the above is classified as Men's' Work. The second major division is Home Demonstration and is arranged similarly to the Men's Work. Within the county agent and Home Demonstration agents reports, racial segregation is also evident. Additionally, there are a small number of special reports on unique projects, studies and trips. These are arranged alphabetically among the departmental reports.

The county agent reports, comprising the bulk of the series, focus primarily on the activities of the county agent and his assistants. Frequently the narrative description of the agent's activities reveal directly or by implication the principal challenges to local agriculture for the year in question. Such challenges range from disease and adverse weather conditions to the economic emergencies of the Great Depression and World War II. Of special note are the reports of the black agents which include many photographs of rural black life and provide a descriptive survey of the crops and livestock of black farm families in North and Central Florida. Departmental reports, the second largest group of records in the series, range from perfunctory to highly descriptive. Some reports provide information on commodity prices, wages, and offer economic analyses. Many include "exhibits" of articles written by the specialists, photographs, graphs, charts and maps as testament to the agent's professional activities.

The home demonstration reports offer a complete description of the varied activities of the home demonstration agents. A number of these reports include photographs of farms, farm homes (interior and exterior), rural crafts and other farm products such as canned foods entered in annual competitive shows. Florida's rural folk are featured in both photographs and narrative anecdotes generally reflecting an improvement effected in living conditions or a triumph over adversity as a result of the supportive efforts of the local home demonstration agent. That part of the series covering the Depression years is particularly revealing of the economic condition of rural Floridians and the state and federal governments' response to their plight.

The early years (1917-c.1929) are incomplete, particularly for departmental reports and county agent reports. Home demonstration was still in its infancy and in fact was not thoroughly distinct from "Men's Work" until the mid 1920s. The series is fairly complete from about 1930 on. A number of new record titles emerge after World War II as others are merged or discontinued.

This subseries is arranged by year. Within years the arrangement is as follows: first the Director's annual report followed by the white district supervisory reports, departmental reports in alphabetical order, white county agent statistical reports (statewide), white county agent narrative reports, negro supervisory reports, negro statistical reports (statewide), and negro county agent narrative reports. Home Demonstration comprises a second major division and is arranged as follows: annual reports, district supervisory reports, specialists' reports, white county agent reports, and negro county agent reports.

Subseries 91b contains the annual reports of the directors, district agents and county agents of the Florida Cooperative Extension Service, which included throughout the period noted the divisions of white men county agents, negro men county agents, white women home demonstration agents and negro women home demonstration agents. The series also contains departmental or specialist reports covering specific fields in agriculture (i.e. agronomy, dairy husbandry, soil and water Conservation, and vegetable production).

The county agent reports, comprising the bulk of the series, focus primarily on the activities of the county agent and his assistants. Frequently the narrative description of the agent's activities reveal directly, or by implication, the principal challenges to local agriculture for the year in question. Such challenges range from disease and adverse weather conditions to major marketing crises, such as that with which the citrus industry was forced to deal in the postwar years. Additionally, these reports document the general introduction of chemical and mechanized agriculture in Florida, the beginning of the decline of the family farm and the rise of the agribusiness corporation, particularly in the specialized agriculture of South and Central Florida.

Departmental reports, the second largest group of records in the subseries, are less descriptive, more rote and repetitive than in Subseries 91a. Nevertheless, many of the same specialists continue to provide economic analyses of contemporary industries, especially through the various exhibits which serve as supportive material behind the main reports.

The home demonstration reports offer a description of the various activities of the home demonstration agents. However, unlike Subseries 91a, there are few photographs, nor the anecdotal material. These reports do reflect the sweeping changes which occurred in U. S. society in the postwar era including the widespread availability of rural electric power and the concomitant introduction of labor-saving devices, especially for women in the home. One file documents the rapid transformation of Seminole life as epitomized by the transition from the traditional palm-thatched Chickee to air-conditioned concrete block on slab with carport.
