Northern Luzon Research Journal (ISSN 1908-5990)

Effective January 1, 2015, the Northern Luzon Research Journal (NLRJ) is renamed as Philippine e-Journal for Applied Research and Development (ISSN 2449-3694). Changes were made on the journal’s objectives and editorial policy, reflecting the publication’s shift into a national and an open-access journal. Otherwise, the publisher and the editorial address remain the same.

The Northern Luzon Research Journal came out with its first volume in 2007, followed by volumes 2, and 3-4. The articles in these volumes (published in print versions) are archived in this site for continuing access.
