ANDREW LIH was an academic in new media and journalism for ten years, at Columbia University and Hong Kong University. He has been a commentator on new media, technology, and journalism issues on CNN, MSNBC, and NPR. Lih is based in Beijing.

Since Wikipedia was launched online in 2001 as "the free encyclopedia that anyone can edit," it has blossomed to more than a billion words spread over 10 million articles in 250 languages, including 2.5 million articles in English, according to Wikipedia cofounder Wales in the foreword. Lih, a Beijing-based commentator on new media and technology for NPR and CNN, researched Wikipedia and collaborative journalism as a University of Hong Kong academic, and he has been a participating "Wikipedian" himself for the past five years. He notes the site has "invigorated and disrupted the world of encyclopedias... yet only a fraction of the public who use Wikipedia realize it is entirely created by legions of unpaid and often unidentified volunteers." Other books have surfaced (How Wikipedia Works; Wikinomics), but Lih's authoritative approach covers much more, from the influence of Ayn Rand on Wikipedia cofounder Jimmy Wales and the "burnout and stress" of highly active volunteer editor-writers to controversies, credibility crises and vandalism. Wales's more traditional earlier encyclopedia, the peer-reviewed Nupedia, began to fade after he saw how Ward Cunningham's software invention, Wiki (Hawaiian for "quick"), could generate collaborative editing. Tracing Wikipedia's evolution and expansion to international editions, Lih views the encyclopedia as a "global community of passionate scribes," attributing its success to a policy of openness which is "not so much technical phenomenon as social phenomenon."
