This chapter summarizes and describes the methodology used to generate and analyze the literature for the ESRC Review Chapters (3, 8, 11, 14, 16, 18, and 22). A core goal of the project was to undertake a systematic literature review and synthesis to identify gaps in current research. This process included Delphi reviews, digital and manual coding of the literature to identify topics and trends, and stakeholder engagement. The first section describes the project team and its participants, what they contributed, and how other stakeholders were engaged. The second section identifies the initial scoping areas and how these were used to identify seven primary domains, to which separate project teams were assigned. These scoping areas included the use of theory and methods. The next section introduces the Delphi process, the eight administrations and six related workshops, based on the initial scoping areas. Key questions, topics, challenges, and literature identified through the Delphi and workshop activities were then used as comparisons to, and guidelines for, the literature reviews. The project developed narrative reviews from the database of over 6,000 publications, using a variety of digital humanities tools and manual content analysis (to code for theory, method, and population sample). The digital tools included concept mapping and topic analysis, and were used to identify the most frequent topics or concepts and related terms or themes. Manual content analysis was used to summarize main discipline, theories used in empirical work, theory development, empirical methods, population studies, and data analysis methods.
