Information technology refers to computer technologies that consist of hardware, software, network, infrastructure, and procedures to collect, process, store, protect, and present electronic data/ information in speech, written, graphic and multimedia forms (Igwe, 2011, Castagna & Bigelow, 2022). The essential components of information technology in library systems according to Library and Information Science Network (2022) include: Computer Systems which consist of input devices (keyboard, optical character reader, mouse, optical mark reader, bar-code reader, scanner, voice data entry), processing devices (Central Processing Unit (CPU)), output devices (monitor, printer, speaker, headphone and projector) and storage(memory) devices (hard disk drive, CD/DVD drive, USB flash drive and so on). The components of IT also include network systems (Modem, local area network, metropolitan area network, wide area network and cables), software (Koha, SOUL, GreenStone, Dspace, etc.) and databases (Author database, Bibliographic database, and full-text database). For example, IITA Knowledge Center subscribed to bibliographic and full-text databases.
Janakiraman and Subramaniah (2015) postulated that the earth is experiencing a digital landscape revolution that has changed the possibilities for library work advancements and modified the required library performances. Information Technology operation in the libraries refers to the use of computer technologies in such a way that the activities of the libraries, such as ordering, cataloguing, classification, reference and information services, can be done quickly with the help of IT. Areas of information technology practices in libraries include:
