Preliminary data from measuring time variations in the differential energy spectra of galactic cosmic ray lithium nuclei in the ridgidity range of 0.5–100 GV are presented for the first time. The measurements were made for the period from 2006 to 2014 with annual averaging based on data from the PAMELA experiment. Selection criteria for lithium nuclei are constructed, their efficiency is estimated, and the acceptance of the instrument is determined. The behavior of the obtained spectra is consistent with variations in solar activity over the considered time interval.
