We review the capability of e+e− and e−e− colliders to detect the
virtual exchange of Kaluza-Klein towers of gravitons within the large extra
dimension scenario of Arkani-Hamed, Dimopoulos and Dvali and in the localized
gravity model of Randall and Sundrum with non-factorizable geometry.Comment: 10 pages, 5 figs, LaTeX; To appear in the Proceedings of the 3nd
