ProQuestA big multi-subject global perspective database for scholarly journal articles and other sources.
Useful for providing an overview of a topic or issue. Contains background information and context and is very useful as a starting point for research - especially if you are new to a topic!
Contains the latest research on very specific topics and often contains in-depth analysis. Journal articles are published more quickly than books so can be used to find more up to date information.
This includes government or non-government organisation (NGO) reports, guidelines and statistics. They often contain an overview of an issue as it applies to a specific region, state, country or worldwide.
