You can read a 24 page PDF file preview of all theses published since 1997. You also have the option to purchase a copy of the thesis.
The default Basic search page allows for general keyword searches across all indexes using "and", "and not", "and or" to link the keywords as appropriate. Click on the More Search Options tab for specific title, author, subject and institution (school) searches, and to browse indexes of authors, institutions and subjects. These indexes allow you to add the word or phrase recognised by the database to your search (ie University of Oxford (United Kingdom), not Oxford University).
The Advanced search tab (at the top of the page) enables keyword searching in specific indexes, including author, title, institution, department, adviser and language. If you are unsure of the exact details of thesis, you can use the search boxes on this page to find it by combining the key information you do have.
In both the Basic and Advanced search pages you can also limit the search by date by using the boxes at the bottom. Use the Search Tools advice in both the Basic and Advanced pages to undertake more complex and specific searches. Within the list of results, once you have found the record that you are interested in, you can click on the link to obtain a full citation and abstract. You can use the back button on your browser to return to your list of citations.
The Browse search tab allows you to search by subject or by location (ie institution). These are given in an alphabetical list. You can click on a top-level subject to show subdivisions of the subject. You can click on a country location to show lists of institutions in that country. At each level, you can click on View Documents to show lists of individual theses for that subject division or from that location.
In Browse search, locations and subject divisions are automatically added to a basic search at the bottom of the page. You can search within a subject or location by title, author, institution, subject, date etc, by clicking on Refine Search at the top of the page or More Search Options at the bottom of the page.
