From the creators:
The purpose of this project is to create a free, open simple dictionary for students to use. The words in the dictionary will reviewed for quality and appropriateness and ultimately "frozen" for export into a variety of formats, including text, PDF, ebooks, wikis, web, etc., for use on a variety of platforms.
The site also includes a build-your-own-glossary tool that allows users to construct glossaries for their own books, units, courses, or web sites and export them to text, html, rtf, pdf, or wikitext.
This is a mass collaboration project, and we hope that you will stop by and add a definition or two.
From FAQ page:
The dictionary is public domain. Anyone may use it for whatever they like.
