A library consortium means a union of libraries composed of formal or informal agreements for common purposes. Domestic libraries increase their price bargaining power by joining a joint purchasing consortium to subscribe to expensive overseas electronic resources and thus increase the effectiveness of the subscription process. Domestic library joint purchase consortium has been divided into the Web DB-centric ACE consortium and the electronic journal consortium until it was merged into the KESLI consortium in 2017 under the government`s policy of unifying task on electronic resources joint purchase. In the process of operating the two consortiums separately, from general guidance on resources to complex subscription conditions, the proposal has been operated differently by supplier and resource type. Therefore, considerable effort and care was required from the library s point of view to understand the proposed content of the electronic resources. In this study, the proposed items of two consortiums are compared and analyzed to develop standardized proposal models. It is expected that this will help streamline the e-resource subscription business for both suppliers and participating libraries. In addition, a study on constructing database of subscription information could be conducted based on the results of this study.
