Digital media have revolutionized information sources and advances in Information and Communication Technologies (ICTs) and have dramatically enhanced information provision. The process of information management has become very challenging and complex. Libraries as centres for learning, teaching and research can no longer cope with information management through the use of traditional methods. To this end, the study was aimed at examining the application of ICTs to management of library information resources in selected Nigerian Federal University Libraries(NFUL) with regards to type of library information resources, type of ICT facilities available and being used, where these ICT facilities are applied in libraries operations and routine, staff ICT competence in the management of library information resources and challenges of ICT facilities utilisation in the management of library information resources in NFUL studied. Survey research method was adopted. Three hundred and thirty six (336) library technical staff from six (6) NFUL were used as sample size for the study. Questionnaire, interview and observation were the instruments used for data collection. The data collected were presented and analysed using descriptive and inferential statistics. The study found among others that books, newspapers, and magazines with a mean score of .9911, .9702 and .9524 respectively, were the major types of library information resources available and frequently used in the libraries studied. Computers with a score of 323 (96%) and internet facilities with a score of 292 (87%) were the most available ICT facilities available for the management of library information resources. Computerized exit doors with a score of 106 (32%) is less available ICT facilities in the libraries studied. lack of ICT policies with a score of 226 (79%) and power outage with a score of 262 (78%) were some of the major challenges facing the NFUL studied. The inferential analysis showed that there was significant difference among the NFUL studied in the type of ICT facilities available and used for the management of their library information resources and there was no significant difference among the NFUL studied staff ICT competences in the management of information resources. The study concluded that digital media have revolutionized information resources and the advances in ICT have dramatically enhanced information provision not only in the selection, ordering, acquisition, processing, storage and retrieval of library information resources but also improved staff productivity. It is expected that the NFUL can fully utilize the benefit of ICT facilities, especially, the digitization of local contents, institutional repository, functioning websites and a policy on ICT information resources management. The challenges of ICT utilization in the libraries if not properly handled will reduce their potentials to achieve the goals and objectives of their parent institutions. The study recommended among others that, the NFUL should use Open-source library information management software and DSpace content management system and document management to manage the library information resources.
