fichaus
Fichaus is a term that can refer to several things, most commonly a type of document or record-keeping system. In a historical context, a "fichau" might denote a physical card or slip of paper used for cataloging or indexing information. This could be found in libraries, archives, or administrative offices, where each card would hold specific details about an item, person, or event. The concept is similar to a card catalog or a ledger entry, serving as a structured way to organize and retrieve data before the widespread adoption of digital systems.
More broadly, "fichau" can also be used metaphorically to describe a collection of data or a profile.
