The museum's fictional registry designated each finalized entry immutable: later notes could be added separately, but the stored original text could not be altered. A temporal chart ordered the exhibition preparations by when tasks began and ended, while a separate plan showed where the displays would stand. An equinox panel paired the Sun's apparent crossing of the celestial equator with approximately equal day and night. A student checked that the qualifying word remained in the caption before the final version was stored.

The immutable original stayed available when a later annotation corrected an explanatory mistake, allowing readers to distinguish the first record from the subsequent comment. The temporal chart helped volunteers schedule their work without confusing sequence with the physical layout of the room. The equinox panel retained the idea of approximate equality instead of replacing it with a claim of exact equality. The class reviewed each kind of information on its own terms before combining the pieces in a public display.
