Volunteers at the English Wikipedia and SOS Children have today launched The Wikipedia Selection for Schools. The Selection is about the size of a 15 volume encyclopaedia with 24,000 pictures, 14 million words and articles on 4,625 topics. It includes the best of Wikipedia as well as many thousands of pages of extra material specifically selected to be of interest to children who follow the UK National Curriculum and similar curricula elsewhere in the world.
The selection is organised around National Curriculum subjects
The articles have been cleaned up and checked for suitability for children
