How this works
Each cell is a weighted overlap: across every adult title tracked at either branch, we compare the lower and higher branch demand-pressure values, then divide the sum of shared pressure by the sum of combined pressure. Books with strong demand at both branches count more; books strong at only one branch lower the overlap. Diagonals are self-matches (—). Branches are grouped by region (North / Central / South Brooklyn) for readability, and only the lower triangle is shown since the matrix is symmetric. If a book isn’t in one branch’s tracked pool, that side counts as no observed signal — not proof of zero real-world demand.
