The study investigated the provision of online databases by librarians for research among academics of polytechnics in Katsina state, Nigeria. The objectives of the study includes finding out the types of online databases provided by libraries for research among academics of Polytechnics in Katsina state and identifying challenges associated with the provision of online databases provided by libraries for research among academics in the Polytechnics under study. An exploratory sequential research design was used for this study, which targeted a population of librarians across the three (3) polytechnics in Katsina State. These included the Federal Polytechnic Daura (FPD) in Daura Local Government, Hassan Usman Katsina Polytechnic (HUK) in Batagarawa Local Government, and the Katsina State Institute of Technology and Management in Katsina. A purposive sampling technique was applied to select participants in which three (3) heads of the libraries were purposely selected. Data was collected using an interview schedule, and the reliability of the instrument was tested using credibility by audit inquiry. The data collected using the interview schedule was analyzed using thematic analysis and Nvivo version 15 was used in familiarization, categorization, coding, generating and naming of themes to ensure proper interpretation of the qualitative data. The participants under study were coded from P1 to P3 and the data were presented and categorized under the demographic data of participants in Table 1. The finding revealed a significant gap in providing online databases, with P1 reporting no databases provided while P2 and P3 provide access to a few online databases such as Elsevier, EBSCOhost, and JSTOR. This disparity highlighted a low outcome on research productivity, as some institutions lack essential academic resources. As such the study recommended that the polytechnic libraries should invest in reliable digital infrastructure to ensure stable access to different online databases. This includes improving internet connectivity, securing uninterrupted power supplies, and updating systems regularly.
