The children's encyclopedia "Discovery of the World by Youth" was published by the Terra publishing house as a translation of a series by the French publishing house Gallimard dedicated to world history. Major scientists and artists from France and other countries took part in the preparation of the encyclopedia. The “Discovery of the World by Youth” series is a publication designed for visual perception, which awakens the reader’s imagination while providing him with the necessary information. Covering the period from antiquity to the present day, the encyclopedia sees its task as helping the discerning and inquisitive reader 10- 15 years to discover the civilizations that have shaped our history for thousands of years. To design each topic (natural history, history, science and technology, literature, etc.) a specific light code is used: Red - history; Green - natural science; Blue - science and technology; Yellow - art; Brown - literature.
