TRB’s National Cooperative Highway Research Program (NCHRP) Report 542: Evaluating Cultural Resource Significance: Implementation Tools examines information technology (IT) tools that are designed to improve and streamline the National Register evaluation of cultural resources. The report highlights IT prototype tools that include a searchable database of historic contexts and a collection of National Register evaluation documents.
