Purpose The purpose of the paper is to: check both of the product and technical items and propose a technology classification framework with a roadmap for omni-channel library; draw the technical association diagram and maturation of the time of developing the omni-channel library; predict the trends of omni-channel library development architecture. Design/methodology/approach The method to carry out this study were secondary data analysis and experts' interviews. The data were collected 80 cases of omni-channel and academic literature, then identified and drawn as a technology roadmap. Furthermore, smart technology experts and researchers were interviewed to not only examine and define the technical association diagram but also predict the market and technology maturation time and predict the trends of omni-channel library. Findings Owing to the continuous improvement of smart technologies, technology channels of delivering digital content have been changed. Content providers will confront numerous challenges in the future. There are several literature and practice findings in this paper. In addition to building a roadmap, technical association diagram and maturation time for omni-channel library, based on market integration and product value, this paper proposes an omni-channel library development architecture. Originality/value The results of this study can be used as practical applications in developing library channel integration strategy. In addition, this study provides insights into future studies in the field of digital content channel.
