Before the Folly became a part of the Met, each English county was connected to a specific practitioner (known as a County Practitioner). They took care of magical 'problems' that the local authorities couldn't handle.
The County Practitioners kept records of all their cases (Incident Books) and sent them, or a formal report of them, to the Folly, at the end of every calendar year. The Folly, in turn, didn't manage to arrange them in any logical order or cross reference them.
