  We review the electronic stopping power data within the IAEA database,
assessing the abundance and scarcity of available data as a function of energy
and collisional systems. Our analysis includes an examination of the
experimental values, their evolution in time, the dispersion among data, and
trends of the more recent measurements. Additionally, we provide comparisons
with SRIM-2013 calculations for select cases of interest. Notably, we identify
sparsely measured systems and energy regions, emphasizing the pressing need for
new, reliable data and independent theoretical predictions.
