It has been nearly a decade since Gerring first published Case Study Research: Principles and Practices. In both editions of his textbook, Gerring’s intent is always to make the subject understandable to new learners. Recognizing the time lapse between editions, he appropriately updated and expanded the second edition to match the development of case study methodology since 2009. The 2017 edition offers five sections, with a generous number of tables and figures contained throughout to complement his subject. Parts One and Two look at the history of case study research in social science disciplines, offer exemplary works using case study research, define terms (useful for working in the unsettled environment of case study work), and discuss case selection, with chapters on both descriptive and causal case studies.
