ABSTRACT
This chapter describes the history of secondary qualitative analysis, starting with B. G. Glaser in 1962. Glaser identified the initial phase in secondary analysis as focusing on the researcher questioning the comparability of the primary data. Glaser identified other benefits of secondary analysis, such as “economies,” which included it being a less expensive process and economy in time since secondary analysis can be accomplished faster than having to collect data. J. West and P. Oldfather labeled their secondary analysis of qualitative research “pooled case comparison,” which begins with raw data. Sociologists in the United Kingdom and nurse researchers in Canada and the United States took the lead in the early publications on qualitative secondary analysis. J. Heaton published an article on secondary analysis of qualitative data in Social Research Update. Heaton identified three main modes of qualitative secondary analysis: formal data sharing, informal data sharing, and self-collected data.
