Karen Antell et al. have published "Dealing with Data: Science Librarians' Participation in Data Management at Association of Research Libraries Institutions" in College & Research Libraries.
Here's an excerpt:
This study, a survey of science librarians at institutions affiliated with the Association of Research Libraries, investigates science librarians' awareness of and involvement in institutional repositories, data repositories, and data management support services at their institutions. The study also explores the roles and responsibilities, both new and traditional, that science librarians have assumed related to data management, and the skills that science librarians believe are necessary to meet the demands of data management work.
