Abstract: Weak emission lines (WELs) of metals are observed in sharp-lined spectra of mid- to late-B type stars. The WELs are detected over a range of element abundance and are found among both chemically-normal and chemically-peculiar stars. The characteristics of this ubiquitous phenomenon are reviewed and their potential for the study of inhomogeneous stellar atmospheres is presented.
