Subject As has been said in the introduction to the previous volumes, this biblio­ graphy 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 envi­ ronment, involved in its production, distribution, conservation, and descrip­ tion. Of course, the ideal of a complete coverage is nearly impossible to at­ tain. However, it is the policy of this publication to include missing items as VIII INTRODUCTION much as possible in the forthcoming volumes. The same applies to countries newly added to the bibliography.
