The four earlier articles in this themed section are based on presentations at a workshop convened to explore challenges in using qualitative longitudinal methods for policy-related research, with particular focus on data analysis and interpretation. Together, they provide useful pointers to the scope of qualitative longitudinal approaches, and extensive discussion of management and analysis of the particular and complex data produced. Readers who are interested in pursuing themselves a qualitative longitudinal approach to policy-related social research will want also to look to a wider literature to enhance their understanding of issues to be taken into consideration, and to explore the range of methods and options. The aim of this review article is to provide some ideas about the kind of literature likely to prove helpful. The bibliographic references for this review article are supplemented by the guide to sources which completes this themed section.
