Abstract: A compact disc storage book is formed with board book pages having pockets therein to receive compact discs. The board book is comprised of folded, printed signatures adhered to one another. A hard cover is attached to and covers the pages to protect the pages and compact discs from damage or contamination. The board book has an expandable spine, which increases its size or thickness from its smaller empty size to its larger, filled size when filled with compact discs. In the preferred method of making this storage book, the signatures have been printed and slit to form the CD receiving pockets prior to being folded on a signature folding machine. The folded signatures are fed by feeders of a signature gathering machine in proper sequence onto a gathering conveyor. The signature gathering machine has a programmable glue applicator to form the glue pattern including the glue pattern for the accordion fold, expandable backbone for the book form.
