When you need to get other student's Ph.D thesis for your reference, how do you get it? Some people upload their Ph.D. Thesis to arXiv.org, but not everyone do so. Many University librararies have their alumni's Ph.D. Thesis in PDF format. However, students from other universities cannot get the file from outside the University. (Caltech is one of the exceptions) For example, I need to get Ph.D thesis from University of Maryland Baltimore County.
