Your handout should be rather short; I limit mine to one page, front and back. It should have a header with the pertinent information about your presentation (title, location, date, YOUR NAME and contact information, etc.), a short description of what you are presenting ( a little different from the abstract, basically giving a little more information in addition to what is in the abstract), and providing citations for your information sources and suggestions for where to find further information on the subject you are speaking on. This is not a copy of your Power Points or your written speech.
