How to turn a library into an arena for intellectual battle? The linguistic quest "Book Secrets: Treasure Hunt" invites schoolchildren and students to decipher codes, solve riddles, and follow the traces of ancient cultures, uncovering the treasures of the book world using intellect, logic, and imagination. Mysterious writings, secret passages, ancient civilizations, and language codes - all this becomes a reality in the linguistic quest "Book Secrets: Treasure Hunt". This is not just an event in a library, but a real adventure where participants are required to engage their imagination, resourcefulness, and team spirit. Participants - schoolchildren and students - will go through four stations, each of which opens a new stage of the quest: riddles, language knowledge tasks, logical games, and creative challenges. All of them are connected with the culture of ancient peoples and the collections of the foreign literature department. Here, knowledge is not an abstract theory, but a tool for searching, analyzing, and unexpected discovery. This is how the book space comes to life, turning into a territory of searches, discoveries, and fun. The quest not only entertains but also educates. It introduces participants to the library's book collection, the possibilities of the electronic catalog, and helps to look at linguistics from a completely new angle. This event is a great opportunity to step beyond textbooks and see how exciting working with texts, words, languages, and symbols can be. The host, Daria Troyanova, a librarian in the foreign literature department, transforms the space into a living map of knowledge, where each step brings you closer to the solution, and each mistake can become a hint. If you are interested in languages, mysteries, riddles, and unusual learning formats - this quest is definitely worth your time. Entertainment in Yekaterinburg is collected on our website.
