The aim of the Atlas is to provide an overview of the spectral characteristics of Be stars in both the far UV and optical wavelength ranges and of their variable behaviour when data are available. Be stars have been frequently observed with the International Ultraviolet Explorer (IUE). The IUE archives contain an enormous amount of information on these objects. After one decade, in 1988, more than 2000 high resolution spectra obtained in the short and long wavelength ranges for about 190 Be stars were stored in the IUE data bank. In part I, we illustrate the recent phase transition of Pleione (HD23862, 28 Tau) from Be-shell to Be star. In part II, selected spectral region containing lines of special interest for Be star modelling (NV, CIV, SiIV, AlIII, FeIII, and MgII for the far UV and Hα and Hβ for the optical region) are presented for all the Be stars observed with IUE up to 1988, that is for 166 Be stars.
