The sources sheet
Every sheet in The Practice File rests on dated public captures of the practice's website, its own published pages, and standard veterinary references.
The file is built from dated captures, not from memory. The primary source is the public archive's record of the practice's website, which holds its pages at intervals across more than a decade. Those captures show two distinct eras: an early site built on a veterinary hosting template with a large topic library, and a later site carrying the same practice with a warmer, pampered-pets tone.
What the archive kept
The captures preserved the homepage at several dates, the full navigation trees of both eras, the service and medical menus, the wellness plan pages, the team pages, and the published directions and hours. They also preserved the shape of the client library: a long shelf of veterinary topic pages plus member extras, from printable puzzles to pet memorials.
What the archive could not keep
The archive kept pages, not people. Appointment books, medical charts, payment records and the daily traffic of a working hospital never touched the public web, and the file says so wherever a sheet reaches that edge. A capture can show that a team page existed and what it listed; it cannot show what happened in the exam room.
The general references behind the sheets
Where a sheet explains what a veterinary term means, it leans on the standard public references of the profession: the associations that publish care guidelines, the manuals a practice would itself hand to a client, and the regulatory pages that define what a hospital may claim. These are cited beside the sheets that use them.
What the file does with silence
A gap in the record is written as a gap. If the archive does not show when a page changed, the sheet does not invent a date. If two captures disagree, both are kept. The file's job is to describe what the record holds, and to mark the edge where the record stops.
