rebuilding corners
The repair and reconstruction of the corner or
corners of the covers of a book that have become
worn, soft, bent, mashed, or broken. Corner
rebuilding generally involves the application of
paste or other adhesive between the plies of the
board. The adhesive is sometimes injected between
the plies by means of a hypodermic syringe. If a
part of the corner is missing, or so badly damaged
that it cannot be rebuilt as described above, the
covering material and board paper are lifted,
permalife paper cut to proper size is glued to
both sides of the board, and the corner is then
rebuilt by packing the space between the permalife
paper with shredded blotting paper mixed with an
adhesive, plastic wood, etc. (173 , 236 )
