Wikipedia. So...how accurate is it?

As a general information source, Wikipedia works quite well. It's a very good resource for two main areas: the factual/well known subjects which are also covered by other encyclopedias, and for information about subjects that wouldn't have any comprehensive amount of data on them in any particular place otherwise.

For major topics like historical figures and basic principles and facts about a major subject, it does a very good job of providing facts and information at pretty much the same pace as a normal encyclopedia. And also, for subjects that otherwise wouldn't really get any attention in a normal encyclopedia (facts about a certain movie or game series, the history of a company, data about technologies, etc.), it's a nice resource when you wouldn't really be able to easily find any information on those subjects anywhere else. For those topics, about the only other place you'd find data on them would be random websites dedicated to those particular subjects, but often they aren't as comprehensive as Wikipedia and sometimes are wrong more often than Wikipedia.

It's weakest when it comes to the more controversial subjects or highly debatable information, or about specific people. For those, there's a higher chance of having false or outdated information being posted and vandalism. But usually those are areas that aren't going to be covered by many other sources without being prone to bias or factual innacurracies as well, so it's a bit of a toss up since you'd just be kinda screwed in general if you're looking for research on those topics.

In general Wikipedia is a good source, especially since they almost always have links that cite their sources and usually give a warning before parts that may have innacuracies are don't cite where the information is from. Of course it's mainly just good to use as a starting point or to get a basic overline of a subject, and occasionally pages will be sabotaged (I've rarely seen that outside of the heated debatable subjects, though), but overall it's a good source that offers a large range of facts quickly.

Just remember that the information there is usually paraphrased to begin with, so there's not much point to taking specific quotes from it and referencing it directly when you can use the original source that's cited at the bottom of the page for it.

Jam it back in, in the dark.
