Abstract (from CDS):

A survey of 261 giants in the globular clusters M3, M13, M15, and M92 carried out with the Hydra multiobject spectrograph on the WIYN 3.5 m telescope has identified no stars with Li I 6707 Å resonance lines stronger than 20 mÅ. The limiting equivalent widths of the lithium line provide upper limits of logε(Li)<+0.0 at Teff=4500 K and logε(Li)<+1.0 at Teff=5000 K. The absence of lithium-rich stars in the sample suggests that the percentage of giants exhibiting enhanced lithium abundances in globular clusters is low.
