Free online encyclopaedia Wikipedia could soon be available on a CD as volunteers work on an offline version of the website. A preliminary version of the CD has already been released earlier this month, with Wikipedia hoping to become available to those without access to the internet - although this obviously destroys Wikipedia's aim of allowing users to contribute to the encyclopaedia themselves. The CD, which can be purchased for $13.99 plus postage, is intended to be of a higher quality than the online version with all bad language and vandalism is being removed. Although the current version only features 2,000 articles, it likely to slowly expand to become a comprehensive offline encyclopaedia to compete with the likes of Britannica and Encarta.
