These ebooks are available on the ProQuest eBook Central platform. You need a username and password to access them. To get access, ask your teacher to contact the library or look at the content and access page of the platform 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.
