To understand ETDs, what NDLTD is, how it works, and the benefits of NDLTD, it is necessary to educate those involved, such as students who will create and submit their ETDs, as well as the library staff members who will be participating in NDLTD and administering their local system. To help educators prepare digital library (DL) courses supportive of their goals, our DL curriculum group has been developing educational modules and conducting field analyses since January 2006. This paper is a follow-up to our previous study of the subject distribution of ACM DL papers, JCDL papers, and D-Lib Magazine articles. In this paper, we focus on the selected DL modules that might help scholars conduct their research and share their knowledge.
