On the value distribution of derivatives of zeta-functions

This set of transparencies concerning derivatives of zeta-functions was found on a shelf near Selberg's desk. The approach developed herein was mentioned to D. Hejhal during a conversation at the 1988 Nordic Math Congress in Trondheim. Where Selberg actually lectured on this topic is currently unclear. (A look at page 1 shows that the date for such a lecture would have to be September 1989 or later.)
