The study consisted of three parts: First, bibliometric data were combined with inputs from Swiss open access publishers, institutional open access experts as well as information on journal websites to identify Swiss Diamond Open Access journals and their main characteristics. Second, seven semi-structured interviews with editors of select Diamond Open Access journals were conducted to generate a thorough understanding of their workflows, infrastructures, business models, challenges and opportunities. Third, based on the inputs from the interviews, three surveys were designed and sent to authors/reviewers, editors, and representatives of hosting and funding institutions of Swiss Diamond OA journals.enreport
