# Experts and sources

The people and organisations whose published work cad-agent's rules and checks stand on: 122 publishers and 80 named authors, in 238 read sources. They did the work. cad-agent cites it by name and never copies it. A rule, check or page that relies on a source names it by id: a `[ref:<id>]` tag in text (which the site links to the source), a module's source table, a material's `source` or a process rule's `source`.
