Since core scholarly journals have been digitalized, demands on the perpetual access and long-term preservation of subscribed digital information resources by libraries are increasing. Various institutions and organizations have performed the preservation activities of digital scholarly resources for the purpose of responding those demands. This paper illustrates the National Digital Archive(NDA) system proposed and developed by KISTI and discusses on the NDA strategies which aim to improve the usability of archived journal articles. In addition, NDA strategies of KISTI have been compared with those of international researches and the economic validity of NDA has been verified by analyzing NPV, BCR and IRR. Legal system for improving the application of the archived data should be studied next and high value-added data services have been suggested as our future studies in the final section.

Evaluation indicators reflecting recent digital environments are needed as a tool to increase research library's competitiveness and productivity. Especially, research libraries have different subject backgrounds and there are many one-person libraries. In this study, we developed new evaluation indicators based on the draft indicators made in 2007 considering these environmental elements so that it may be used easily and applicable to various research libraries. In developing the new indicators, we reviewed other library type's indicators and listened carefully to the comments from expert librarians in the research libraries through several meetings. After developing the indicators, we made a survey in order to verify its validity as well as its effectiveness and also made a test evaluation for research libraries. The proposed indicators will contribute in evaluating the current level of Korean research libraries and promoting them to the future-oriented libraries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
