Daniel Defoe 
The Complete Tradesman 

A handbook intended for young men in 18th century England. Its value today is as a window into everyday life of that time, as background of understanding history or for writing historical novels, or perhaps as a guidebook for time travellers. According to Wikipedia: Daniel Defoe (1659/1661 [?] — 1731), born Daniel Foe, was an English writer, journalist, and pamphleteer, who gained enduring fame for his novel Robinson Crusoe. Defoe is notable for being one of the earliest practitioners of the novel, as he helped to popularise the form in Britain, and is even referred to by some as one of the founders of the English novel. A prolific and versatile writer, he wrote more than five hundred books, pamphlets, and journals on various topics (including politics, crime, religion, marriage, psychology and the supernatural). He was also a pioneer of economic journalism.
