The spin lattice relaxation rates and the absorption line shapes of ^7Li in both Li_2B_4O_7 single-crystal and glass samples were measured from room temperature up to 900 K. At lower temperatures the dominant contribution to the relaxation rate was the spin-phonon interaction in both samples. For the single crystal the relaxation caused by the diffusion of Li ions became significant above 760 K, and the narrowing of the absorption line started at about 650 K. For glass the narrowing of the line started at room temperature and the effect of the diffusion of Li ions on the relaxation rate was dominant above 400 K. From these results the correlation time r_c of the fluctuating field at Li sites in the crystal and glass of Li_2B_4O_7 was obtained.
