Librarians as professors

In response to Matt's post below, I could see librarians moving in more of a direction of being more professorial in the future. I think it's already a trend with more librarians teaching credit courses on research.

Some of the skills Matt mentions on reading sound like skills that are (or should be) taught in basic English classes on reading and writing. But there is overlap with research as well. In the research class I teach, I definitely teach some of those things (when to skim, reading the texts critically, etc.).

So... do you think librarians will move toward doing some of the things English professors do now? Or working more with them to supplement what they do?
