In this work, 14 even-parity ${2l2l}^{\prime }{\mathrm{nl}}^{″}$ $(n>~3)$ resonances of lithium are calculated by using the saddle-point complex-rotation method. Among the 14 resonances, four are ${}^{2}P$ resonances, four are ${}^{2}D$ resonances, and six are ${}^{2}S$ resonances. Relativistic corrections are evaluated with the first-order perturbation theory and the mass-polarization effect is also included. The Auger widths are studied. The partial Auger widths are calculated for the individual open channels and the total width is obtained by coupling the important open channels. These results are compared with recent theoretical and experimental data in the literature.
