BACKGROUND Valuable learning derived from public health practice can be captured through practice-based case studies, also known as practice examples. Practice examples of participatory interventions supplement the evidence base by providing information on the complexities of implementation in communities. This paper reports on a Public Health England project to build a bank of community-centered practice examples based on robust processes of collection and curation. METHODS The multidisciplinary project had three phases: (i) development and piloting a process to collect practice examples, (ii) refining review processes and gathering further examples via national and regional teams (iii) maintenance of an accessible collection on the library platform. RESULTS The project resulted in a searchable collection of 55 practice examples illustrating participatory approaches in public health practice. The collection shows diversity in terms of settings, population, focus and type of approach used to work with communities. A secondary outcome was the development of generic guidance and templates for further collections on public health topics. CONCLUSIONS This project illustrates how information on the implementation of community-centered approaches in real-life contexts can be gathered and disseminated through a transferable process. Having collections of practice examples supports knowledge exchange in public health as learning is shared.
