Van Nostrand's Concise Encyclopedia of Science

If you are trying to write a science encyclopedia for under 700 pages, the biggest issue is probably what to leave out. In part, this is dictated by what type of audience you are targeting. The editors seem to have pitched this offering towards a high school crowd, or perhaps also towards primary schools. A nice, colourful reference, with text that is carefully written to a general audience. Understandably, there is an emphasis on topics with visual appeal. Nothing wrong with this, if it gets readers into the book.The book is also economically priced. Affordable to school libraries on tight budgets.
