Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.

New peculiar stars identified on objective-prism plates
Tables are presented of 90 peculiar stars revealed on more than oneobjective-prism plate and 61 suspected peculiar stars based on a singlespectrum. The set of 90 peculiar stars includes 48 Ap, 32 Am, and 10stars with composite spectra. The stars were identified as peculiarstars during spectral classification in the regions of the OBassociations Cyg OB4, Cep-Lac OB1, and Cas OB9. The spectralcharacteristics of the different types of peculiar stars are discussed.
