The focus of the Study Guide is the literature review within a dissertation or a thesis, but many of the ideas are transferable to other kinds of writing, such as an extended essay, or a report.
Guidance will be available via your own department or school and via the relevant Information Librarian.
There may also be key sources of publications for your subject that are accessible electronically, such as collections of policy documents, standards, archive material, videos, and audio-recordings.
You can find the contact details for the Information Librarian for your own area via the Library web pages.
This person can help you identify relevant sources, and create effective electronic searches: anything on your research area is a good start. You may also want to make a clear decision about whether to start with a very narrow focus and work outwards, or to start wide before focussing in. It is a good idea to decide your strategy on this, rather than drifting into one or the other.
