The Harriman Institute supports and furthers the research of its faculty and students through lectures and conferences, the annual Core Project, Working Papers seminar, and research programs; hosting postdoctoral fellows and visiting scholars; the publication of Studies of the Harriman Institute; and, finally, financial support of projects by Institute faculty and students through the PepsiCo grants for research travel and study, undergraduate fellowships, faculty research small grants and publication grants. (See Student Affairs for student grants and fellowships and Reseach for faculty research support.)

Taken together, the library resources of Columbia University together with the famed collection of the New York Public Library offer Harriman researchers one of the richest concentrations of materials for Russian, Eurasian and East European studies in the world.
