Abstract: “The word around us is full of physical variables that are constantly changing. If we can measure these variables and represent them as a digital quantity, then we can equally record, restore, retrieve, re-organize, manipulate and use them in some other ways in quantities imaginably through information dissemination and services. To tackle the battle imposed upon by the “Omnipotent” National Union Catalogue in Nigeria, the professional librarians have to equip themselves with the mentality of keeping abreast of current developments in the library networking technologies with determination and develop their own “Home-made Schemes” that would form a framework for a National Union Catalogue if not for Africa as a whole but for Nigeria as a Nation. This paper illustrates the importance of cataloguing and classification in organizing our libraries and attempts how the professional librarians can brainstorm together to develop a framework of a comprehensive list of a National Union Catalogue”
