Compare branches
Pick any two of the 12 tracked BPL branches to see what they share, what each over-indexes on, and how their adult-fiction tastes diverge.
Sunset Park + Coney Island40%normalized overlapNormalized overlap: first ranks each branch's fresh tracked titles by demand pressure and converts those ranks to within-branch percentiles. It then divides the sum of the lower percentiles by the sum of the higher percentiles across titles tracked at either branch. A missing title counts as zero observed signal. This compares relative demand without letting one branch's raw score range dominate.39 shared · 24 only Sunset Park · 21 only Coney Island

How this works
Each cell is a normalized overlap. We rank every fresh title by demand pressure within its own branch, convert those ranks to percentiles, then compare the lower and higher percentiles across titles tracked at either branch. This puts every branch on the same relative scale. A title missing from one branch counts as zero observed signal. Diagonals are self-matches (—). Branches are grouped by region (North / Central / South Brooklyn) for readability. The matrix is symmetric, so both directions show the same value. 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.
