I need two books. How can I find them on the Internet? Is it possible to study them on the Internet?
Gilbert, J.B. (2005). Clear Speech. Cambridge: CUP.
Hedge, T. (2000). Teaching and Learning in the Language Classroom. Oxford: OUP. Chapter 5.
Both are fairly recent publications so are in copyright and most unlikely to be found on the net. Neither of the Presses is particularly free with its material.
Second hand copies are very cheap - perhaps you have a friend or relative who can get one for you?
