The Dagstuhl Research Online Publication Server (DROPS) is an open-access publishing platform operated by Schloss Dagstuhl – Leibniz Center for Informatics. It functions as a digital library for high-quality, peer-reviewed research in computer science.

DROPS contains more than 20,000 published articles, along with supplementary materials, evaluated research artifacts, and reports from Dagstuhl Seminars and Perspective Workshops. All content is published as open access and assigned persistent identifiers such as DOIs to ensure long-term accessibility and citability. Long-term preservation is ensured through established external partners, including the German National Library and Software Heritage.
