Search engines

Search engines can be a useful starting point for discovering resources on the Internet, though often it may be better to use a specialist subject gateway.  It is important that you are critical in judging the quality of the information that you find on the Internet. Our page on how to use search engines, including Google, effectively also describes the limitations of search engines. You should use MetaLib if you wish to research a topic thoroughly. This will give you references to quality, usually refereed, published research.
