Below you can see some ebooks on presentations and public speaking that are available on the ProQuest eBook Central platform. You need a username and password to access them. To get access, see this page of the user guide or ask your instructor to contact the library

There's a guide to the platform available here with a lot of information on the platform and its features, which are summarised in a one-page quick guide

Basically, you can read these books online or download them to your device. Reading online offers more features, like making notes and highlighting text, while if you want to read them on your device you need to install a special app, so we'd recommend reading them online.
