We present a new compilation of Wolf-Rayet (WR) galaxies and extra-galactic Hiiregions showing broad emission drawn from the literature. Relevant information on the presence of other broad emission lines (N iii λ4640, C iv λ5808 and others) from WR stars of WN and WC subtypes, and other existing broad nebular lines is provided. In total we include 139 known WR galaxies. Among these, 57 objects show both broad and C iv λ5808 features. In addition to the broad (stellar) emission, a nebular He ii component is well established (suspected) in 44 (54) objects. We find 19 extra-galatic Hii regions without WR detections showing nebular emission. The present sample can be used for a variety of studies on massive stars, interactions of massive stars with the ISM, stellar populations, starburst galaxies etc. The data is accessible electronically and will be updated periodically.
Key words: galaxies: starburst / galaxies: stellar content / galaxies: ISM / stars: Wolf-Rayet
