Encyclopedia articles written by professional writers to give concise and accurate overviews of a wide range of topics, people, places, and things.
Wikipedia is similar to other encyclopedias, except that the authors can be anyone instead of professional writers. This means that some writers are experts in the topic, and others are regular people like you and me.
Like all encyclopedias, Wikipedia should be used as a starting place for research and not as an authoritative source for your research projects.
This tutorial explains how to use Wikipedia as an exploratory tool and where it can appropriately fit in the research process.
