Abstract
Globular clusters (GCs) are among the oldest objects in the universe. By studying their Li content, insights can be gained about both the cosmological lithium problem and about the ubiquitous multi-population identified in GCs and, hence, about their chemical enrichment history. We will present the results of two spectroscopic campaigns aimed at studying the Li content of un-evolved stars in the GCs ωCen and M4.
