Detailed simultaneous radiative transfer-statistical equilibrium calculations have been performed for lithium in atmospheres of solar metallicity G-M dwarfs and subgiants. Model atmospheres of stars with 3500 ≤ \Tf ≤ 6000 K, 3.0 ≤ \lgg ≤ 4.5 have been considered. The behaviour of level populations, source functions and curves of growth for the lithium doublet at λ670.8~nm and two subordinate lines of astrophysical interest (λ610.3~nm and λ812.6~nm) are discussed. For the coolest atmospheres of our grid we find that the dependence of non-LTE equivalent widths and profiles on gravity is very weak. The computed LTE and non-LTE curves of growth are given in tabular form.
