While enormous in size and vast in scope, the NRS is not entirely comprehensive. In the 1890s, West retroactively brought all pre-1880 published cases of all lower federal courts into the NRS framework by compiling them into the "Federal Cases" reporter. But West never did the same thing with all U.S. Supreme Court cases which predate the publication of the "Supreme Court Reporter", nor with all published state cases that predate the start of the NRS regional or state-level reporters. The NRS does not include opinions from state trial courts, courts administered by territorial governments (as distinguished from federal territorial courts), Indian courts, or administrative agencies at either the federal or state level. Certain opinions from federal courts of appeals, federal district courts, and state appellate courts are not selected or designated for publication. However, all these materials can be found separately on legal research databases.
