A playful and provocative exploration of mighty Wikipedia: how it was built, why it thrived, and what we lose as its ideals disintegrate.

One of the keystone inventions of the twenty-first century, Wikipedia is the largest repository of human knowledge ever made, with editions in 343 languages read by millions every day—all created by unpaid, mainly amateur, and mostly anonymous volunteers. In this entertaining book, journalist Richard Cooke delves into Wikipedia's fabled creation, its extraordinary success, and its profound effects on politics, business, literature, and society. He explores the site's shifting role in establishing fact in a time of deep uncertainty about truth and authority; the often hilariously fierce debates between "Inclusionists" and "Deletionists" about what is worth knowing and preserving, and who gets to decide; and the great peril Wikipedia faces today from bots, political division, and artificial intelligence. The Last Best Place on the Internet is a fascinating journey into the hidden world of one of the most vital—and most endangered—cultural achievements of our time.
