In the three years since the Boulder Wolf-Rayet Conference, a great deal of observational material has been collected and processed. That conference was, of course, the stimulus for a great deal of the work, since it made clear where some of the large gaps in our observational knowledge lay. As a result the greatest progress has been in directions which were previously underexplored, and some subjects which were actively pursued before the last conference have been left almost untouched since. Thus, much of what was said in 1968 need not be reviewed again; I can confine my attention to topics which have been significantly changed by new observations. The new observations comprise, in particular, the systematic observation of spectra of many stars at moderately high dispersion, observation of far ultraviolet spectra, and discovery of some WR stars in M33 - the first outside of our own Galaxy and the Magellanic Clouds.
