The journal was founded in 1995 and the first issue volume 1, numbers 1 and 2 made its debut in June 1995. The ten-man Editorial Board was headed by Barth N. Ekwueme. The sixteen maiden articles reflected the goal of the journal as spelt out in the maiden editorial entitled: “A step in the right direction”. The aims were and are still to publish authoritative articles that reflect worldwide research advances and evolving trend in the pure and applied sciences and relevant to its environment.

The journal grew rapidly in terms of number of manuscript submission and accepted for publication. It was regular and articles published were peer-reviewed. The journal was not established for selfish interest. Those in other fields of research including Humanities, Engineering, Social Sciences demanded from the Founder the floating of journals to publish articles in their area. Yielding to their demand, the Founder established the Global Journal series comprising the journals listed under profile. That was in 2002. since then the Journals had grown and have contributed to the promotion of many academicians. It has also been rated highly by International Network for Scientific Information (INASP) based in Oxford.
