The article paper was on conceptual and theoretical framework of digital information resources usage by undergraduates: Implication to higher institutions education in Delta and Edo of Nigeria. It revealed the concept of digital information resources [DIRs] and model theory that related to the study. Finding shows that DIRs are use to low extent in all the university libraries. The finding also shows negligence on the part of university management of Federal University of Petroleum Resources Library that have no digital information resources at all. Another findings showed that constraints to students effective use of Digital Information Resources in the University Libraries are epileptic power supply; non-availability of online databases; inadequate number of computers to access digital information resources; inadequate bandwidth; Network problems; lack of skill to access digital information resources in local and foreign databases; Lack of formal training on internet use; Server slowness and frequent breakdown of digital resources. The implications to higher institutions education in Delta and Edo States include: It has been empirically proved that three university libraries in Delta and Edo state used for the study made DIRs available for their undergraduates. This implies that the institutions moved with current trends of digital age in higher institution. The study has revealed that the Digital Information Resources are used to low extent by undergraduates in UNIBEN; AAU; DELSU and FUPR. The implication is that undergraduates that utilized digital information resources to low extent will lag behind in their research, learning and assignment process in this digital age. The students could not compare themselves with other institutions of higher learning that use DIRs to a very great extent.
