The Royal Library is a significant institution that houses a vast collection of books, manuscripts, and other important documents. Often associated with royal families or governments, these libraries serve as cultural and historical repositories. They aim to preserve knowledge and provide access to information for researchers, scholars, and the public. One of the most famous examples is the Royal Library of Alexandria, which was established in ancient Egypt. This library was renowned for its extensive collection of works from various cultures and was a center of learning in the ancient world. Today, many countries maintain their own royal libraries to safeguard their literary heritage.
