ProQuest Dissertations & Theses Global is updated weekly and features 24 indexed and searchable fields, including full text searchability for the entire text of full-text dissertations.
ProQuest Dissertations & Theses offers five Look ups or browsable indexes, so you can easily find spelling or format variations of, for example, an author's name or a subject name. You can find the Look up links in the advanced search page and they are available for the following searchable fields: Author, Advisor, Subjectname, Index term and School name. For a description of these fields, please see the Searchable fields table to the right.
Note: Look ups are also available from the Command Line search (through the Look up terms link).
To use and locate a Look up or browsable index, select the field from the Advanced Search pull-down menu. If a Look up is available, under the search row you will see a link to the Look up. Other Look ups and browsable indexes will be listed in the Limit To section of the Advanced Search page.
Select the Look up link and then you will see a browsable and alphabetical index for that field. There are some indexes that will not display an alphabetical list before searching for the term, rather you will have to enter a term first, and then the alphabetical list of matches will display.
Once you locate the index term that you would like to add to your search, mark the item, and then click the Add to search button. The index term will now appear in the advanced search form along with the appropriate pull-down menu selection.
