An Encyclopedia of Freemasonry and Its Kindred Sciences, written by Dr. Albert G. Mackey and first published in the late 19th century, is a monumental reference work designed to provide a comprehensive overview of the history, philosophy, symbolism, and jurisprudence of Freemasonry. It was intended to serve as a complete library under one cover for Masonic scholars and members. The work remains a widely recognized, fundamental, and authoritative text on the subject of Freemasonry, frequently reprinted for its historical and educational value.
