"Arbuthnotiana: The Story of the Ghost of St. Albans (1712). Catalog of Dr. Arbuthnot's Library (1779)" is a unique publication that combines two works by the eminent English physician and journalist John Arbuthnot. The first part of the book is an interesting non-fiction novel about a ghost that appeared in St. Albans, where the author investigates supernatural phenomena. The second part is a catalog of Arbuthnot's own library, which allows the reader to immerse himself in the world of books and publications that he collected throughout his life. By combining the mystical and scientific in one book, the author reserves the opportunity to observe beyond the boundaries of the known and open new horizons of knowledge.
