The World Bank catalogs its documents this way using a
program called Teragram. (And the World Bank generates
a lot of lengthy documents in a very wide variety of
topic domains.)
Teragram:

Slides from a presentation by Denise Bedford, the head
of metadata operations at the World Bank, about their
metadata/search system:

(The slides that most directly address Teragram and
how they use it start with slide 44.)
