Case Study Method

The case study method is a qualitative research strategy that involves an in-depth, detailed investigation of a single case or a small number of cases within their real-life context. The case could be an individual, group, organization, event, or any other specific subject, and the goal is to explore its complexities, identify key factors, and draw insights that contribute to understanding broader principles or phenomena. In the context of Library and Information Science (LIS), the case study method is often used to explore particular problems, challenges, or successful practices in library services, information systems, or user behavior.

1. Definition and Overview

A case study is a research approach that focuses on a specific instance or phenomenon. It involves collecting detailed, comprehensive data from various sources (such as interviews, observations, documents, and reports) to provide a deep understanding of the case in its real-world context. The case study method allows researchers to explore complex issues that are difficult to capture through other research methods, making it particularly useful for studying social processes, organizational behavior, or unique instances.

Case studies can be descriptive, explanatory, or exploratory, depending on the research objectives:

Descriptive Case Study: Describes the case and its context in detail.

Explanatory Case Study: Focuses on understanding the cause-effect relationships behind the case.

Exploratory Case Study: Seeks to explore new areas or hypotheses for further research.

2. Types of Case Studies

Case studies can vary depending on the research focus and the method of data collection. The types include:

a. Intrinsic Case Study:

Description: This type of case study focuses on the case itself because it is of intrinsic interest to the researcher. The purpose is to gain a deeper understanding of a particular case.

Example: Investigating the implementation of a new library management system in a specific library to understand the process and outcomes.

b. Instrumental Case Study:

Description: In this type, the case is studied to provide insight into a broader issue or theory. The case serves as an example to explore a particular phenomenon or challenge.

Example: Examining a library’s efforts to increase user engagement through digital platforms as a case to understand the challenges faced by libraries in the digital age.

c. Collective Case Study:

Description: Involves studying multiple cases to gain a broader understanding of a phenomenon. This is often used when one case alone may not provide sufficient data to address the research questions.

Example: A study examining several libraries’ responses to the COVID-19 pandemic to understand the range of strategies used to serve users during lockdowns.

3. Key Characteristics of Case Studies

a. Focus on a Specific Case:

The case study method is centered on a particular case or instance, whether it's an individual, organization, event, or process.

Example: A case study of a specific academic library's initiative to implement a new information retrieval system.

b. Contextual Understanding:

The method emphasizes understanding the case within its real-life context. Researchers consider the social, cultural, economic, and organizational environment to gain insights into the case.

Example: Studying a library’s information-seeking behavior by considering the socio-economic factors and technological infrastructure of the community it serves.

c. In-Depth Data Collection:

Case studies typically involve the collection of multiple types of data, such as qualitative data (e.g., interviews, focus groups) and quantitative data (e.g., usage statistics, surveys).

Example: Collecting interview data from library staff and users, as well as usage data from the library’s website and digital platforms.

d. Exploration of Complex Issues:

The method is particularly effective for exploring complex issues that cannot be easily reduced to simple variables or measured quantitatively.

Example: Investigating the challenges and opportunities for libraries in providing equitable access to information in rural areas.

4. Data Collection Methods in Case Studies

The case study method typically involves a variety of data collection techniques, which may include:

a. Interviews:

Description: Interviews are a common data collection method in case studies, providing firsthand insights from individuals involved in the case. These can be structured, semi-structured, or unstructured.

Example: Interviewing library staff and patrons to understand their experiences with a new library service.

b. Observations:

Description: Researchers may observe the case in action to gain insights into behaviors, interactions, and practices.

Example: Observing how library users navigate the physical space of the library or use digital resources.

c. Document Analysis:

Description: Analyzing documents, reports, meeting notes, or archival materials related to the case provides valuable secondary data.

Example: Analyzing annual reports or strategic plans of a library to understand the goals and challenges it faces.

d. Surveys/Questionnaires:

Description: Researchers may distribute surveys or questionnaires to gather broader quantitative data on a case.

Example: Conducting a survey to assess library users' satisfaction with newly implemented services.

e. Audio-Visual Materials:

Description: Photos, videos, and audio recordings can serve as data sources, especially in cases that involve events or public interactions.

Example: Analyzing video footage from library events or presentations to assess engagement and participation.

5. Steps in Conducting a Case Study

Conducting a case study typically involves the following steps:

Step 1: Define the Research Question or Objective:

Clearly outline the specific question or problem that the case study aims to address. This helps guide the entire research process.

Example: "How did a specific library successfully implement a digital archiving system?"

Step 2: Select the Case:

Choose the specific case that will be the focus of the study. The case should be relevant and able to provide insights into the research question.

Example: Selecting a library known for its innovative approach to user engagement through technology.

Step 3: Collect Data:

Gather detailed data from multiple sources, such as interviews, surveys, observations, and documents. Use triangulation (multiple data sources) to ensure validity.

Example: Interviewing library administrators, conducting surveys with users, and reviewing library usage statistics.

Step 4: Analyze Data:

Analyze the data collected through coding, thematic analysis, or pattern recognition to identify key insights or themes.

Example: Identifying themes related to the challenges and successes in the implementation of the digital archiving system.

Step 5: Report Findings:

Write a detailed report or case study that includes a description of the case, the research findings, and conclusions. Provide recommendations based on the analysis.

Example: A case study report detailing how the library's implementation of a digital archiving system improved resource accessibility for users.

Step 6: Interpret and Generalize:

Based on the findings from the case, draw broader conclusions or implications that can inform theory or practice. While case studies are focused on a specific instance, they can provide insights that apply to similar situations.

Example: The findings might suggest generalizable best practices for libraries attempting to implement digital archiving systems in the future.
