Description
Books are treated as living structures in this specialized computational tool, created for binders sewing signatures by hand, conservators caring for fragile parchment, paper makers forming sheets from cotton rag pulp, and archivists slowing the decay of nineteenth century newsprint. It follows how sewing threads swell and relax as humidity shifts, how iron gall ink slowly migrates through fibers, how lignin rich papers grow brittle with time, and how tension settles along a raised band spine. These gentle insights help reveal whether a volume can endure another hundred years or is quietly nearing its final chapter.
