The commitment of National Library of Indonesia (NLI) as a Non-Ministry Government Institution (NMGI) in utilizing information technology can be seen from one of the organization's mission that is developing a diversification of library service based on ICT (Information and Communication Technology). In carrying out this mission, the entire library services implement the information technology optimally through e-Government services. To measure the implementation of e-Government at NLI, the assessment has been conducted by using Indonesia e-Government Ranking (PeGI). PeGI assessment in the National Library of Indonesia has been implemented and published in 2013 and 2014. However, in 2015 and 2016 PeGI assessment has not been implemented. Therefore, it is important to analyze and evaluate e-Government implementation in the National Library in 2016. There are five (5) dimensions to be assessed in PeGI, including policy, institutional, infrastructure, application, and planning. Data was obtained by interviews, collecting the supporting documents with a qualitative approach and descriptive data analysis. The result indicates that the e-Government implementation in NLI overall is in the good category, and there are increasement from 2013 to 2016 assessment. However, there are two (2) dimensions under the average score, i.e., policy and institutional dimensions. NLI is expected to make a better improvement and development of e-Government implementation.
