I review the theory of broadening of metallic spectral lines by neutral hydrogen atom collisions developed by Anstee, Barklem and O'Mara. I discuss why the theory works, while is able to retain the wide range of applicability needed for astrophysical applications. I discuss the present status of large scale calculations for many spectral lines for neutral and singly ionized species. Some examples of application to analysis of cool star spectra will be discussed.
