A critical review of the available experimental data on Stark widths and shifts for spectral lines of non-hydrogenic neutral atoms and positive ions has been carried out. The review covers the period from 2001 through the end of 2007 and represents a continuation of earlier critical reviews up to 2000. Data tables containing the selected experimental Stark broadening parameters are presented with estimated accuracy. Guidelines for the accuracy estimates, developed during the previous reviews, are summarized again. The data are arranged according to elements and spectra, and these are presented in alphabetical and numerical order, respectively. A total of 41 spectra are covered. Comparisons with comprehensive calculations based on semi-classical theory or on semi-empirical method are made whenever possible, since the comparison with theory has often been a principal motivation for the experiments.
