La riqueza de las naciones
Published as part of the 1976 Glasgow Edition of the works and correspondence of Adam Smith. It consists of two sets of lecture notes that were apparently taken from Smith's lectures of the 1760s, along with an 'Early Draft' of The Wealth of Nations. The same material had also appeared as "An Early Draft of Part of The Wealth of Nations" and as "Lectures on Justice, Police, Revenue and Arms".
