In this paper, a summary of existing experimental data published in the period of time between 1954 and 2015 is reviewed and presented in a tabular form for average L shell fluorescence yields taken from different sources. First, a critical examination of these data using the weighted average values (omega) over bar (L-W) is presented. Then, an interpolation using the well-known analytical function ((omega) over bar (L-W)/(1 - (omega) over bar (L-W)))(1/4) as a function of the atomic number Z is performed to deduce a new empirical average L shell fluorescence yields for elements in the range 23 <= Z <= 96. New theoretical calculations based on the configuration mixing Dirac-Fock method were performed for a few elements and are presented in this work. The results are compared with other theoretical, experimental and empirical values reported in the literature and a reasonable agreement has been obtained.
