Academic librarians interested in collaborating with faculty in online courses often express questions about their role, level of involvement, and activities. This article provides a list of best practices to guide those developing embedded librarian services. The practices are drawn from a review of the literature, a case study of one embedded librarian's experiences, and a mixed methods study of embedded librarianship at six institutions. The resulting best practices will help embedded librarians collaborate effectively with faculty to create a positive learning experience for distance students. (Contains 1 table.)
