Not that this is a subject particularly related to interior design, but nevertheless it has become an important tool in most of our lives, so I do think it is worthwhile to feature it: London designer Rob Matthews has printed the full version of all featured Wikipedia articles and bound them into the possibly thickest book on this planet.
The self-updating and information balancing nature of Wikipedia obviously doesn’t work in this version anymore, but it still is impressive to see in tangible form the sheer information that the site consists of.
It contains more than 5000 pages and can probably be named the most influential encyclopedia of the 21st Century.
