The case histories listed in this bibliography were originally selected for the purpose of developing a system for analyzing the process of directed cross-cultural change. In confining this selection of case histories to efforts of introducing ideas or techniques into another society, the normal range of technical aid projects was included, such as community development, agricultural extension, education, public health, and so forth. Most of the cases are identified as one of six basic project types, but there are a few, such as resettlement cases and organization of clubs, that do not readily fit into these categories. They are labelled as miscellaneous. Also, there are some cases that are a combination of two or more of the six types. For example, wells may be drilled both for drinking water and irrigation. These cases are identified by each relevant project type. The primary grouping of the cases is by country or political unit in alphabetic order (Angola to Venezuela). Under each country they are grouped according to basic project type, then alphabetically by author. Each citation is followed by a statement of the goal of the innovator and, when available, the size and time period of the project.
