The study "Systematization and Analysis of Crowdsourcing Providers and Crowd Work Projects" has now been published as Volume No. 324 in the Hans Böckler Foundation's "Study" series. In it, authors Jan Marco Leimeister, Shkodran Zogaj, David Durward and Ivo Blohm examine different crowdsourcing platforms, the number of which has risen sharply in recent years and the limits to their growth are not in sight. The study provides insights into basic forms of crowdsourcing, but also into employment opportunities within the framework of crowdwork. Based on this, analyzes corresponding control, remuneration and coordination processes in the context of crowdwork.
