Using dictionaries and encyclopaedias help you understand the key terms and concepts, giving definitions as a starting point. This is part of the initial planning stage, when you are analysing the assignment brief, considering keywords and building a search strategy. It may also be necessary to define some of the key terms in your work.
When writing your work, consider citing definitions from the academic books and articles which will make a better impression. You will also gain understanding of key terms and concepts from your lectures and seminars. Your lecturers will recommend sources in lectures and seminars; make sure you check the unit reading list and lecture notes for direction to the best sources.
Do not cite and reference Wikipedia in your university work.
Use a database BU Library subscribes to called CREDOReference instead of Wikipedia. It has definitions from credible, reliable sources.
