Q: Is Wikipedia a good source on the internet for research
A: I think that Wikipedia is a good source on the internet for research. I usually begin with Wikipedia as their layout / content delivery is excellent.
Although it is a publicly edited collective, it has been extant for many years now and poor quality posts are more rare as “bogus” information has been weeded out over time with a world of editors working on the various subjects.
For very new or highly specific topics I would not trust any one source, but for general research I use and trust Wikipedia. (eg. I found that on Wikipedia someone had listed the Princess of Japan as the Valedictorian of her high school class. Since she was my classmate I know it was not her, but rather it was Roo Canfield, I edited the Wikipedia document and brought that up to speed).
So I think that ANY source can have bogus information but that the accuracy of Wikipedia is good enough to count it as a source as reliable as any.
I use and recommend multiple sources, always, and I include Wikipedia as one of those sources.
