Good source for pre PhD level papers/dissertations in Mathematics I am looking for a good source to get my hands on some pre PhD level maths papers/dissertations, because I want to get a better feeling what is expected. (i.e. BSc and MSc Dissertations)

My department is unfortunately not at liberty to make MSc Dissertations available for copyright reasons, so I am stuck with asking individual people. In order to get a good overview I'd really like to get my hands on a much bigger selection of papers though, so I'm looking for a good online sources.
Your best source of such information would be to look for electronic repositories that are at least partially "open." The openThesis repository offers one such source, and you might find some information on sites like academia.edu. 

An alternate source would be to look at individual school's repositories. For instance, MIT's DSpace offers copies of many recent MIT thesis and dissertations, which can be previewed by anyone, although you need to be a member of the MIT community in order to be able to download and print documents from the site.
