  We examine outstanding issues in the analysis and interpretation of the halo
Li plateau. We show that the majority of very Li-poor halo Li-plateau stars (5
out of 8) have high projected rotation velocities vsini between 4.7 and 10.4 km
s^-1. Such stars have very different evolutionary histories to Li-normal
plateau stars, and hence cannot be included in studies of Li depletion by
normal halo dwarfs. Uncertainties in the effective temperature scale for
metal-poor stars continue to challenge the analysis of Li.
