How to read these comparisons

Shared systems: The number of matching category–product relationships. A product recorded under two categories counts once in each category. Duplicate records within the same category count once.

Smaller inventory overlap: Shared systems divided by the smaller district’s recorded total. This can reach 100% even when district inventories differ greatly.

Combined inventory similarity (Jaccard): Shared systems divided by the combined distinct inventory: total A + total B − shared systems.

Instruction / Curriculum: Include all systems, count only products classified in Instruction / Curriculum, or leave that category out. All counts, totals, percentages, verification summaries, and shared-system lists use the selected scope. This filter uses the systems catalog category, not the separate curriculum catalog.

Verification: “Verified records” includes the SDLA verified and high-confidence statuses. It describes the records, rather than guaranteeing present-day district use. Confirm details with the district before making decisions.

Ranking: Highest shared count first. Ties use combined inventory similarity, then smaller inventory overlap, followed by district names. Filtering or selecting verified records only recalculates the ranking and totals.
