The primoridal lithium abundance is known to be one of the best probes to test the standard as well as the non-standard Big Bang nucleosynthesis theories, and to measure the nucleon abundance in the early universe in the standard Big Bang (SSB) model. We have obtained high-resolution (({lambda})/({delta}{lambda}){congruent}100,000), high signal-to-noise (S/N{approx gt}1,500) spectra of SN 1987A around the Li:I {lambda}6708 A region, using the ESO 1.4m CAT and the Coude Echelle Spectrograph. The non-detection of any lithium feature in our sepctra places an upper limit on the lithium abundance. (AIP)
