A repository is a free online collection of documents, often scholarly.
There are several kinds: repositories maintained by a single university, for its own students' dissertations and theses, and/or its own staff's published research.
This often includes versions of papers published in scholarly journals.
Review the existing papers, Electronic Theses and Dissertations, and other pieces of content authored by your faculty and researchers.
