I have no idea where to go from the Library page on iue.edu, to get to a subject listing of things I could do an informational speech on.
The LibGuide for your class is available here.
Check out the articles tab to see the databases grouped by subject – so, if you’re doing a social topic, you might pick Social Science Journals (ProQuest), SocINDEX with Full Text, or JSTOR from the ‘Social Issues’ box. There are similar boxes for Legal, Education, Economic, Family Matters, Environmental Science, Medical, and more.
Let me know if I can be of any help to you in finding information for your topic.
