EIGHTH GRADE.
1. Book for Mounting Drawings and Pictures.
Heavy cover paper is used for this book and is cut into large folios. Then strips of the same paper about one and one-half inches wide and as long as the book is high, are folded lengthwise in the middle. One of these folded strips is fitted over the back and one inside of each folio, Fig. 51, except the first and last. This provides for the pasting of a mount on each page of the book without making the body of the book thicker than the back. Sewed on tapes. Cover treated exactly as that of the Library Binding, page [27].

It is much easier to handle this problem by making the book of regular sections instead of using the one and one-half inch strips, and then cutting out every 3rd or 4th leaf after it is completed. These leaves are not wasted. They may be used for smaller books.
2. Typical Library Binding. See page [22].
Half leather.
Sewed on tapes.
Double boards.
French joint.
Backed and rounded.
Head cut and colored.
Cord inserted instead of headband.
3. Portfolio.
Bound in leather and paper or cloth. Three boards are cut the same size. The joints between the boards are treated exactly like the back of a case binding, except that leather is used and that the inside of the joints are also lined up with leather. Small boards for the flaps are joined in the same manner to the ends of the middle board. Fig. 52 shows the portfolio with only the leather pasted on. The cover paper or cloth is cut and pasted exactly like that of the Library or Extra Binding.
