About this plate
The catalogue count is a declared gap, but Illinois gives something better and more durable than a count: the programme's CREATION and DEATH thresholds, in statute. 2,000 applications to be born, fewer than 1,000 live sets over two years to be killed. Those numbers will still be true when today's catalogue is stale, and they are the reason this index is worth more than a scraped list would have been.
