Part 1: Typography as Interface
Arial Black is a bold, highly legible font often used for headings and signage. At 16 points, it is large enough to command attention but not so large as to overwhelm. In a library context, typography dictates how information is discovered. Card catalogs, signage, and digital interfaces rely on typefaces to guide users. If a library adopted “Arial Black 16” as its standard for call numbers, section headers, or computer terminals, it would prioritize clarity over ornamentation—echoing modernist principles of functional design.
