See also Editorial functions and the policy guidelines generally.
Editors are in charge of particular subject matters, such as philosophy, music, and chemistry. They enjoy considerable autonomy on issues of content. Editors assign topics to writers and formulate any necessary policy and direction with respect to their own categories, though they are expected to follow and enforce general Nupedia policy guidelines. Also, the editor's approval is required for any article to be accepted as part of the encyclopedia. We wish editors to be true experts in their fields and (with few exceptions) possess Ph.D.'s. The responsibilities involved can be discharged without imposing a serious burden on the editor's valuable spare time.
We wish to encourage all accomplished scholars to consider heading up a category that addresses his or her interests. You can apply very easily online, where you can even upload a CV for viewing by the editor-in-chief or another relevant editor. For more information or general inquiries, please write the editor-in-chief, Larry Sanger, at lsanger@nupedia.com. To apply, we require a CV or resume, as well some means of establishing bona fides (a web page will probably suffice). And please do not hesitate to write any of our present editors for advice.
Like work done building open source software projects and dmoz.org, these are volunteer positions, but, we think, both rewarding and interesting. Nupedia's editorial structure is such that your participation will be a solid addition to your credentials.
