This project report describes the process used to convert the retrospective life history data collected in 1969 at the Center for Social Organization of Schools at the Johns Hopkins University to a more usable form, the writing and testing of computer storage and retrieval programs for the data, and the initial interpretation of data relating to lifelong educational patterns of men. Part 1 provides a description of the unique characteristics of life history data and an explanation of the logic behind the storage and retrieval system. Part 2 contains the documentation for the computer tape including descriptions of each of the 15 life history variables. Part 3 explains the use of the life history Sample Retrieval Program. Part 4 describes the rates, incidence, and duration of educational activities for men in the Life History Sample, including the relationships of relevant background factors and occupational patterns.
