Answer: OWL Powerpoint Presentations on Writing.
RayS. These Powerpoint presentations from the Purdue University Writing Lab cover a wide range of topics on writing. I skipped immediately to “Writing Business Messages.” The presentation was clear. Reminded me of things I had forgotten or paid no attention to and added some helpful information. Presentations also deal with writing résumés and cover letters for employment. Try a couple of these Powerpoint presentations on topics of interest. I think you will find them to be worthwhile. URL is listed below.
