Excerpt from the Introduction: To the student of agriculture in relation to population most material relating to agricultural science as well as sociology and economic history is of interest. From so extensive a field it would be quite impossible to select a well-rounded and usable list of books. Therefore, this bibliography has been limited to (1) those works which deal with quantities of foods - production, export, import, and consumption; (2) those which describe the sources of foods and the means by which they are brought to us; and (3) those which definitely discuss the relation of agriculture to population. In the hope of making the list more useful it has been arranged by continent and by country, with a general group of the books of world-wide interest under which is a group devoted to economic geographies and similar works.
