This data package supports the paper "Interdisciplinary collaboration from diverse science teams can produce significant outcomes", an analysis of papers cited by twenty two synthesis-center-type groups in the USA and France from 2010 - 2020. This package contains three data objects: the first is a collation and classification by research field (using the Australia and New Zealand Fields of Research Classification) of publication outputs by these working groups. Second is a matrix (long format) matching research disciplines to citations of publications in these publication outputs. The third data object is a document of free-text, voluntary feedback from synthesis participants in response to the questions “how effective was group function”; “how satisfied were you with the function of the group?”; and “in your opinion, what were the primary factors that contributed to your working group’s effectiveness or lack thereof”. The groups studied were formed between 2010 and 2015 and sponsored by three organisations. Data collation ceased in August 2020. All data has been anonymized to ensure that none of the sponsoring organisations, synthesis groups or individuals can be identified.
