There is now a Wikipedia for schools. It is a selection of 5500 articles and 34,000 images that fit on a DVD. The articles have been vetted for content so that teachers and students can rely on the material being accurate; this solves a longstanding complaint with Wikipedia, is that it is difficult to gauge the accuracy of any given article. With the material on a DVD, it can be used offline, so Internet access is not required. The DVD will be particularly useful in developing countries where schools do not always have Internet access, or have a very low bandwidth connection that cannot support many students browsing at the same time.
