Theses are uploaded as digital copies to the Graduate School, and technical reports are uploaded to the Carolina Digital Repository.
It is an open-access source that houses user-submitted theses and dissertations and also other works by instructors and researchers affiliated with UND-Chapel Hill.
However, as it houses works besides theses and dissertation and is relatively new, it may not pull up older works.
These papers and reports are not in Davis Library or, for the most part, in the North Carolina Collection or the Libraries' online catalog.
Some departments and departmental libraries have online lists.
Contact the department, or, if there is one, the departmental library for information.
Environmental Sciences and Engineering Master's level students in the Department of Environmental Sciences and Engineering can opt for one of four tracks: a Master of Science degree, which requires a thesis; and the Master of Science in Public Health, Master of Public Health, and Master of Science in Environmental Engineering, which require a technical report.
You will be searching for "thesis ma" or "thesis m a," which will appear as a note in the catalog record.
You can use subject headings, title words, an author's last name, etc., and add "and thesis ma or thesis m a".
They can be found using the card catalog located in that collection or the online catalog.
They do not have subject headings unless they are about North Carolina. Some departmental libraries also have copies but these are also non-circulating.
