Factors such as instructions, payment schemes, platform demographics, along with strategies for mapping studies into crowdsourcing environments, play an important role in the reproducibility of results. However, inferring these details from scientific articles is often a challenging endeavor, calling for the development of proper reporting guidelines. This paper makes the first steps towards this goal, by describing an initial taxonomy of relevant attributes for crowdsourcing experiments, and providing a glimpse into the state of reporting by analyzing a sample of CSCW papers.
