    • Wikipedia, (or ) is a free Internet encyclopedia that allows its users to edit almost any article accessible. Wikipedia is the largest and most popular general reference work on the Internet and is ranked among the ten most popular websites. Wikipedia is owned by the nonprofit organization Wikimedia Foundation. Wikipedia was launched on January 15, 2001 by Jimmy Wales and Larry Sanger. Sanger coined its name, a portmanteau of wikiand encyclopedia. It was only in the English language initially, but it quickly developed similar versions in other languages which differ in content and in editing practices. With articles, English Wikipedia is the largest out of more than 290 versions of encyclopedias on Wikipedia. Overall, Wikipedia consists of more than 40 million articles in more than 250 different languages and , it had 18 billion page views and nearly 500 million unique visitors each month.

      In 2005, Nature published a peer review comparing 42 science articles from Encyclopædia Britannica and Wikipedia, and found that Wikipedia's level of accuracy approached Encyclopædia Britannicas. Criticism of Wikipedia includes claims that it exhibits systemic bias, presents a mixture of "truths, half truths, and some falsehoods", and that in controversial topics, it is subject to manipulation and spin.

    • ABSTRACT: Prior research on Wikipedia has characterized the growth in content and editors as being fundamentally exponential in nature, extrapolating current trends into the future. We show that recent editing activity suggests that Wikipedia growth has slowed, and perhaps plateaued, indicating that it may have come against its limits to growth. We measure growth, population shifts, and patterns of editor and administrator activities, contrasting these against past results where possible. Both the rate of page growth and editor growth has declined. As growth has declined, there are indicators of increased coordination and overhead costs, exclusion of newcomers, and resistance to new edits. We discuss some possible explanations for these new developments in Wikipedia including decreased opportunities for sharing existing knowledge and increased bureaucratic stress on the socio-technical system itself.
