Although most libraries use signs for strictly functional purposes, several have introduced more eye catching designs. Some libraries use fluorescent and even neon colors effectively. One respondent uses pictograms to pull together directional and instructional signage in the otherwise confusing networked environment. Construction Libraries tend to use a combination of sign construction sources, both in-house and outside the library. Library staff members make signs on an ad hoc basis in 47 libraries, and in two libraries an in-house graphic designer makes the signs.
Libraries use a variety of materials for both sign background and lettering.
The background material most often used is paper, followed by acrylic, plastic laminate, and mounting board. Other substances used, in rank order of preference, are Plexiglas, metal, and wood-based products. Some libraries apply lettering directly to the wall surfaces. And, of course, a large number of libraries generate lettering by computer. Libraries list engraved plastic laminate and vinyl letters on acrylic, plastic, or Plexiglas as the most durable materials for signs.
