In order to shed new light on the dispersion of Li in the atmosphere of solar
type stars, a set of 56 solar analogs including 22 solar twins is analysed.
Lithium abundances are derived by comparing observed and synthetic spectra
in the region of Li I line 6707 Å in LTE approximation.
The behavior of Li abundances as a function of the effective temperature Teff,
age, rotational velocities vsini and chromospheric activity log R’HK is
discussed in the context of stellar and galactic evolution.
