The discovery of a lithium-rich giant in the globular cluster M3 (IV-101; Kraft et al. 1999, \apjl, 518, L53) prompted a search for similar stars in a large sample of cluster giants in M3, M13, M15, and M92. A survey of 261 additional giants, carried out with the Hydra Multi-object Spectrograph on the 3.5-m WIYN Telescope, 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 log~\epsilon(Li)<+0.0 at Teff=4500K and log~\epsilon(Li)<+1.0 at Teff=5000K. The absence of lithium-rich stars in the sample suggests that the percentage of giants exhibiting enhanced lithium abundances in globular clusters is low.
