The bibliography this encyclopedia rests on. Tier A is a book, a peer-reviewed paper or an official document; tier B is a practitioner or organisation source. Every published claim names one of these.

The printed sources the corpus rests on. Where a public catalogue record exists we link it; where one does not, we say so rather than link a guess.

Websites and reference works

Organisation sites and secondary references. A practitioner or organisation site is a practitioner source even when it is the system's own.

A source that cannot be checked is not a source. If you find a citation here that does not say what we claim it says, record the page and the problem. The form cannot carry free text yet, so it records the page and the kind of problem, not the passage.
