  We adopt up-to-date 7Li yields from asymptotic giant branch stars in order to
study the temporal evolution of 7Li in the solar neighbourhood in the context
of a revised version of the two-infall model for the chemical evolution of our
galaxy.
  We consider several lithium stellar sources besides the asymptotic giant
branch stars such as Type II supernovae, novae, low-mass giants as well as
Galactic cosmic rays and low-mass X-ray binaries.
  We conclude that asymptotic giant branch stars cannot be considered as
important 7Li producers as believed in so far and that the contribution of
low-mass giants and novae is necessary to reproduce the steep rise of the 7Li
abundance in disk stars as well as the meteoritic 7Li abundance. Lithium
production in low-mass X-ray binaries hardly affects the temporal evolution of
7Li in the solar neighbourhood.
