What if you need a particular thesis and it’s NOT freely available online? You may use interlibrary loan to request a copy
Request a copy via ILL (Interlibrary Loan)
Note: In many cases we can acquire an electronic version, but some theses are only physically owned by the degree-granting institution. Some libraries will loan their copy, some will not. It’s always OK to try, but it’s not a sure thing that you’ll get it.
Find a record for the thesis in LibSearch. If your initial search doesn't find the title, click on the link to search beyond partner libraries. If this search returns a record, click on the Request button and submit the form (note that you need to login to LibSearch to see the option to request). If no record is found click on the link that reads Still didn't find what you need? Click here to submit a request. Fill out the form and submit.

And Last But Not Least
It's always worth trying a search engine--Google, Bing, or your favorite--using quotation marks around the title and perhaps the author's last name, if the title isn't unique--to see if the author has posted the dissertation on the web somewhere. It's surprising how often this is the case.
And for cases where you can't find a free copy, but you CAN find contact info for the author, try to get in touch with the author and ask if they'd be willing to share a copy of their thesis with you. Many people are thrilled that someone is interested in their blood-sweat-and-tears project, and would happily oblige.
