The Book of Discipline refers to two works regulative of ecclesiastical order in the Church of Scotland, known as The First Book of Discipline (1560) and The Second Book of Discipline (1578), drawn up and printed in the Scottish Reformation. The first was drafted by a committee of "six Johns", including leading reformer John Knox. It set out a system of Presbyterian polity on the Geneva model, but the lack of funds meant its programme of clerical organisation and education was largely abandoned. The second book was adopted after the forced abdication of Mary Queen of Scots and was much more clearly Presbyterian in outlook. It placed church supervision fully in the hands of groups of elected church leaders in presbyteries. Source: Wikipedia (en)
