The Li abundance of the T Tauri star BP Tau is determined from both the Li I 6707 and 6103 features, using high-accuracy observations and recent model atmospheres. Other work, based solely on analysis of the 6707 line, has found very high Li abundances in T Tauri stars. A significant difference is found between the abundances derived from the two different lines and no evidence in this star of a Li abundance significantly in excess of the typical Population I value log n(Li) about 3.0. 27 refs.
