Presentations are often given as a form of assessment. You could be required to present in person or produce a recorded presentation or screencast. You will usually need to do some research for you dissertation and are usually required to provide references too so the finding information and referencing guides may be useful to you.
Look at Library Search for books and eBooks on presentations, or see below for selected titles.
You can use the following software to create presentations. Check your assignment brief for which software to use.
