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"). This was revised in 1801 and 1822 and 1833 (the last revision resulting in another change in title to "Rules of Discipline"). Up until this time, the publication was an alphabetical list of the main beliefs and practices of Quakers at the time.
