The ProQuest dissertations are the dissertations saved in the ProQuest dissertation databases. Generally, the ProQuest dissertation databases can be found online. Almost every higher educational institution has its own ProQuest dissertation database.
 
You may order the ProQuest dissertations on the topic similar to yours or related with yours from the ProQuest dissertation database of your university or college. This may turn out to be very useful while conducting your dissertation research. The ProQuest dissertation may contain information, which may serve as a background for your dissertation research, since all the dissertations normally have a chapter containing the review of the literature on the topic. If you have the same (or alike) topic as the ProQuest dissertation, you may get acquainted with the basic information on the topic. Besides, you may find the references to the sources which deal with your dissertation topic in the list of sources of the ProQuest dissertation.
 
What is more, the ProQuest dissertation may serve you as a dissertation template. You may follow its example when writing your own dissertation.
 
It is very easy to find the needed dissertation in the ProQuest dissertation database. These databases normally contain the dissertations abstracts, or, putting it more plainly, the brief overviews of the dissertations. Some dissertation databases provide their customers with a service of searching the needed dissertation by key words. However, it is better to read the ProQuest dissertation abstract before ordering it, because the information presented in the abstract will allow you to understand if you really need the dissertation.
 
You may easily get an access to the college or university ProQuest dissertation database from elsewhere, all around the territory of the educational centre, including your room, the dorm, the library and so on. If you do not know how to do it, you may ask your university mates, or your supervisor.
