High-resolution spectra provide evidence of the Li-I 6707 line in 28 of the stars, and the significance of the results is discussed. The Li-I equivalent widths are presented after correcting for continuum veiling with actual measurements of the veiling itself. Surface spots are found to have a complex effect on the width of the photospheric lines, and the width of the line for V 410 Tau does not appear to change with spot coverage. The results indicate that the model atmospheres and stellar parameters for the T-Tauri stars lead to errors in calculating the Li abundances. The stars have higher Li abundances than meteorites and the local ISM if the T-Tauri stars are hotter than late K. Several effects are discussed which are of an unusual nature including the Li depletion among young low-mass Taurus-Auriga objects and the homogeneous nature of Li depletion among stars with strong and weak emission lines.
