 It contained general advices and regulations, and was the basis of future books of discipline, although the name was formally disclaimed by Friends in 1675.The origins of the current book of discipline can be traced back to a manuscript in 1738 entitled "Christian and brotherly advices given forth from time to time by the Yearly Meetings in London, alphabetically digested under proper heads".The first printed collection appeared in 1783 as "Extracts from the minutes and advices of the Yearly Meeting of Friends held in London from its first institution" (popularly known as the "Book of Extracts").
