Subject As has been said in the introduction to the previous volumes, this bibliography aims at recording all books and articles of scholarly value which relate to the history of the printed book, to the history of the arts, crafts, techniques and equipment, and of the economic, social and cultural VIII INTRODUCTION environment, involved in its production, distribution, conservation, and description. Of course, the ideal of a complete coverage is nearly impossible to attain. However, it is the policy of this publication to include missing items as much as possible in the forthcoming volumes. The same applies to countries newly added to the bibliography.
