Crowdfunding is understood as an alternative form of financing that encourages a large number of individuals (the "crowd") to contribute relatively small amounts of money for the implementation of specific projects, typically through an open call, mostly via the internet. Karin Sattler examines the extent to which crowdfunding is used as a business model by international publishers and what recommendations can be derived for a specialized publishing house. She analyzes crowdfunding, business model approaches, the publishing industry, and practical case studies. From this, Sattler develops a business model approach for "Crowdfunded Publishing," which is intended to serve as a guide for specialized publishers in integrating crowdfunding. It becomes evident that crowdfunding can complement traditional publishing revenues for specialized publishers.
