You'll find some theses and dissertations written by CMU students in our Digital Collection, linked below.
It is also possible to search for dissertations and theses using the Dissertations and Theses Database (see link below). You can limit your search results to master's theses at Central Michigan University by going to More Search Options and entering the name of the university in the box next to University/Institution. Then, under Manuscript Type, check the box that says Master's theses. The results should provide full text, previews, abstracts, or some combination of these.
