This document discusses social science and humanities (SSH) collaborations and interactions with e-infrastructure projects. It notes that the European Commission has funded several domain-specific research infrastructure projects for SSH fields like CLARIN, DARIAH, and CESSDA. These projects often collaborate with each other by having overlapping partners. National projects also bundle efforts across disciplines. Cluster projects aim to do similar things in similar ways. Some e-infrastructure projects have previously worked with SSH communities. While SSH fields are diverse, progress has been made in developing common standards and solutions through projects like DASISH, PARTHENOS, SERISS, and SSHOC. Further collaboration opportunities exist through the European Open Science Cloud (
