More than sixty years ago my grandparents bought me an encylopedia: it was a major purchase for them as they didn't really ''do'' books, but it was a treasure trove for me and I still have it today. It didn't just teach me facts - it taught me how to find out information for myself and how to use an index. It opened my eyes to subjects I'd never considered and widened my knowledge on those I already loved. In format, in size and content it was very similar to ''DK Children's Encyclopedia'' and I can imagine a younger me hunched over it and begging just to be allowed to finish this bit before I went to bed.
