Scholarpedia is a peer-reviewed open-access encyclopedia written and maintained by scholarly experts from around the world. Scholarpedia is inspired by Wikipedia and aims to complement it by providing in-depth scholarly treatments of academic topics.
Scholarpedia and Wikipedia are alike in many respects:
both allow anyone to propose revisions to almost any article
both are "wikis" and use the familiar MediaWiki software designed for Wikipedia
both allow considerable freedom within each article's "Talk" pages
both are committed to the goal of making the world's knowledge freely available to all
