Previous: Introduction
Few systematic searches for WR populations outside
the Local Group (or ``WR galaxies'') have been undertaken.
In this Section we briefly summarise the studies explicitly devoted
to the detection of WR signatures.
A list of candidate WR galaxies resulting from some of these searches
or found loosely in the literature is provided in Sect. 6.
The WR galaxies issued from the searches described below are included
in our list and represent the vast majority of detections.
Let us now briefly summarise the properties of the spectroscopic
and narrow-band imaging searches.
