Abstract: | An historical view of the discovery and subsequent studies of lithium in low-Z stars is presented. The determination of the lithium abundance in extremely low-Z stars, found in the vast Beers, Preston and Shectman survey, is reviewed. The problem of the exact connection between the lithium abundance found in the photospheres of low-Z stars and the true cosmological abundance of lithium is discussed, and identified as the most important problem to be solved in the coming years. |
