Wikipedia:External peer review/JAH2006

"History is probably the category encompassing the largest number of articles", but the collaborative editing makes it unlike virtually any other scholarly work in that field.
Wikipedia articles have numerous authors, many of whom may be anonymous, and there is no expectation that their names are used when discussing their articles.
"This extraordinary freedom and cooperation make Wikipedia the most important application of the principles of the free and open-source software movement to the world of cultural, rather than software, production."
The freedom of reuse allowed by open licensing of content is an important advantage for educational uses.
