The National Library of Portugal, known as the Biblioteca Nacional de Portugal, holds a revered position as the country's national library, serving as a vital hub for legal deposit and copyright matters. Its rich history dates back to the late 18th century when it was established under the name of the Royal Public Library of the Court, through a decree issued on February 29, 1796. This groundbreaking initiative opened the doors to a treasure trove of manuscripts, paintings, books, and other invaluable works that were previously accessible only to a privileged few.
