The library

Expert testimony is concentrated

A small number of expert classes account for most of what is said on a stand in US civil litigation, and the tail beyond them is long and thin. That is what makes a library a finite thing to build, and it is why the order of the build matters more than its size.

The first 5050% covered

About half of all civil expert testimony, because the head of the distribution is very heavy.

15080% covered

Four fifths. The body of medical, engineering and financial testimony is covered.

50090% covered

Ninety percent and the practical ceiling. Past this, each addition buys less than a tenth of a percent.

Our library today: 115About 70% covered

115 expert classes across 19 practice areas. The curve reads higher at 115, but that would be the 115 most-testified classes, so we state it as about 70%.
