Our primary catalog is SouthernSearch. It's a really good place to start looking for resources. It searches all of the ebooks that we have access to and it searches across many of our databases--all through one searchbar! It's a great place to start when you aren't sure quite which database to look in for your particular topic.
It will return both physical and online resources. Since you are an online course, you can look in the left bar of the results to narrow down to only "Full Text Online" resources. This will limit the results to only ebooks and journal articles online. There are many other ways that you can narrow your results in SouthernSearch. You can narrow by date, by resource type, or by whether the resource has been peer reviewed. If you have any questions on this, I or other librarians will be happy to help you.
For immediate help, you can look at a useful page on constructing a search and narrowing results authored by librarian Wendy Hardenberg that I'll include below. It includes a tool to help construct a search string thatyou can use in SouthernSearch or other databases.
Google Scholar doesn't guarantee access to everything that it finds. But it is links to a good deal of material that is focused on scholarly sources and points you towards sources. And, best of all, its search style is exactly what we all know from Google.
