What is 'literature searching'? For any academic work that you have to do – an essay, dissertation or project – you will need to do some reading and searching for information. ‘Literature searching’ just means using the library catalogues, databases and other search tools to find the best sources of information for your task.
This guide suggests a logical, step-by-step approach to doing this.
Specialist dictionaries can be useful for defining unfamiliar terms. In academic essays, you often have to define the terms you are using, even if you know what they mean, so these dictionaries can help. Search for e.g. ‘electronics dictionary’ and limit to Library Catalogue.
