* kacid = Key & Compass ID. The Key & Compass website uses a unique ID code for every work of interactive fiction. It is usually just the first five significant letters and digits of work's title followed by the last two digits of the work's publication year, but when this results in an ambiguous ID, an arbitrary letter is appended to the ID.
