The ProQuest platform provides access to many databases, including the largest online database of theses and dissertations.
These tasks will give you a flavour of how you can use Proquest to search theses and dissertations. You can try these tasks on your own, although they were designed to be done in a classroom with a teacher to support you. Choose the task most suited to your subject area.
For these tasks, you will need web browser software such as Mozilla Firefox or Edge installed on your computer. Talk to your IT support person about this.
