William Attardi on August 26, 2025

The First Edition of the Encyclopedia Britannica Is Published on Dec. 10, 1768  The Encyclopedia Britannica, the oldest continuously published and revised work in the English language, was first made available to the public in Edinburgh, Scotland. This monumental work, which would go on to become a cornerstone of knowledge, marked the beginning of a publication that has influenced generations of scholars, students, and curious minds around the world.  The Encyclopædia Britannica was the brainchild of Colin Macfarquhar, a Scottish printer and bookseller, and Andrew Bell, a Scottish engraver. Together, they sought to create an authoritative, comprehensive, and accessible work that would encapsulate the growing body of knowledge of their time.  What began as a small printing project in Edinburgh grew into one of the most influential reference works in the world, providing access to knowledge and intellectual insight for generations, helping to shape the way we think about history, science, culture, and the world around us. Today, the Encyclopedia Britannica is regarded as one of the most influential reference works in the world. Our personal library to help us learn.  I hear  something better is coming along………
