To evaluate the project "Research in integrated management and services of urban development records, archives, and information" in progress, this paper analyzes "why", "what", and "how" issues of relevant integration research about integrated management and services of urban development records, archives, and information based on a survey of literature at home and abroad. By a comparative study of current integration research status and features, the author gives a critical analysis of the strengths and weakness of the project and provides recommendations for future research.Cross disciplinary studies indicate that ideals of integration can add values to collaboration, innovation,and optimum in managing evidence, information, memory, and knowledge of built environment cross-culture, cross-discipline, cross-domain, and cross institution for enhancing competitiveness and productivity of business. Cross cultural studies indicate that integrated records, archives, and information management as a whole into capital construction project management process, organizational information resources management systems, and the construction of digital urban development archival repository through service-control, process-control, and product-control are fundamental to guarantee the characteristics and quality of records and records system to support evidence-based e-government,e-business, and the sustainability development of digital city. Present studies on integrated management and services of urban development records, archives, and information have limitations on too much emphasis on integration for collaboration and optimum but not enough studies on integration for innovation and broader use.
