How can scholars select cases from a large universe for in-depth case study analysis? Random sampling is not typically a viable approach when the total number of cases to be selected is small. Hence attention to purposive modes of sampling is needed. Yet, while the existing qualitative literature on case selection offers a wide range of suggestions for case selection, most techniques discussed require in-depth familiarity of each case. Seven case selection procedures are considered, each of… 
A Careful Look at Modern Case Selection Methods
TLDR
It is argued that a number of common case selection strategies work well only in idiosyncratic situations and should be abandoned in favor of the more powerful and robust case selection methods that this analytical framework identifies.
Selecting Cases for Intensive Analysis
TLDR
This study revisits the task of case selection in case study research, proposing a new typology of strategies that is explicit, disaggregated, and relatively comprehensive, and arguing that medium-n samples occupy an unstable methodological position.
The Case for Selecting Cases That Are Deviant or Extreme on the Independent Variable
Qualitative and multimethod scholars face a wide and often confusing array of alternatives for case selection using the results of a prior regression analysis. Methodologists have recommended

    Challenges and Opportunities in Qualitative Research

Case study research requires researchers to purposefully select information-rich cases, as they will allow researchers an in-depth understanding of relevant and critical issues under investigation
A Bayesian Perspective on Case Selection
Case selection is a matter of ongoing debate in comparative and multi-method research that combines large-N analysis with qualitative case studies. The voluminous literature contains a proliferation
Three Pathways to Case Selection in IB: A Twenty–Year Review, Analysis & Synthesis
With its focus on locational context, International Business (IB) is a prime candidate for the application of Case Study (CS) methodology. Yet many IB scholars still have doubts about CSs, possibly
Is There a (Viable) Crucial-Case Method?
Case study researchers use diverse methods to select their cases, a matter that has elicited considerable comment and no little consternation. Of all these methods, perhaps the most controversial is
Three Pathways to Case Selection in International Business: A Twenty–Year Review, Analysis and Synthesis
TLDR
The link between case selection and theorizing in CSs is addressed and greater methodological sophistication and transparency of CS selection reporting in IB research is advocated, to raise the standard and status of CS research.
Paired Comparison and Theory Development: Considerations for Case Selection
ABSTRACT Despite the widespread use of paired comparisons, we lack clear guidance about how to use this research strategy in practice, particularly in case selection. The literature tends to assume
Case Selection via Matching
TLDR
Through several applications, it is shown that matching methods have advantages over traditional selection in “most similar” case designs: they ensure that most similar cases are in fact most similar; they make scope conditions, assumptions, and measurement explicit; and they make case selection transparent and replicable.

Most methodological work on case studies understands this topic as a study of a case where the objective is to discover something about a broader population of cases. Yet, many case studies

This paper aims to clarify the meaning, and explain the utility, of the case study method, a method often practiced but little understood. A “case study,” I argue, is best defined as an intensive

The Possibility Principle: Choosing Negative Cases in Comparative Research
A central challenge in qualitative research is selecting the “negative” cases (e.g., nonrevolutions, nonwars) to be included in analyses that seek to explain positive outcomes of interest (e.g.,

TLDR
A unified approach which joins intensive case-study analysis with statistical analysis improves the prospects of making valid causal inferences in cross-national and other forms of comparative research by drawing on the distinct strengths of two important approaches.

TLDR
By concentrating on the logic of testing necessary conditions, this paper attempts to show that the methodological implications of selecting on the dependent variable are much less threatening to the validity of small-n comparative case study work than has often been claimed.
