The staff at most libraries walk through the building to decide where signs are needed, but it is interesting to note that many libraries make this decision by incorporating user input as well. Libraries also monitor users' directional questions, allow a committee to decide, or simply respond to library staff requests when making decisions about where to place signs. Libraries combat vandalism by using reverse engraving on signs, placing vinyl letters on the reverse side of Plexiglas, installing Plexiglas over signs, or laminating signs. Several libraries place signs only in high traffic areas where vandalism is less likely to occur. Temporary Signs One respondent correctly notes that all too often there is a discrepancy between the guidelines and actual practice.
Temporary signs are especially difficult to manage.
In six libraries temporary signs must conform to the same guidelines as permanent signs. Several libraries have guidelines specifically developed for temporary signs, but 44 libraries have no restrictions or guidelines whatsoever. Some libraries simply do not allow hand-lettered signs, and others require that even temporary signs must conform to colors representative of the building. Americans with Disabilities Act ADA has had a positive effect on library signage. Although 37 libraries report that their signs do not yet conform to ADA requirements, a significant number of libraries are incorporating raised lettering and Grade II Braille for the newer signs.
