Engineering and Technology Journal is the official peer-reviewed journal, publishing under the license of Creative Commons Attribution 4.0 International (CC-BY). Engineering and Technology Journal (ETJ) was first established in 1977 in a printed version only. In 2005, ETJ was published online. The journal was initially named "Scientific Journal" and had a print ISSN of 1681-6900 in 1977. However, in 1983, it underwent a name change and became "Engineering and Technology Journal," while still retaining the same print ISSN of 1681-6900. Then, after initiating its first electronic website in 2005, the journal adopted an online ISSN of 2412-0758. ETJ publishes original articles and review papers in the fields of engineering and science. The journal uses a double-blind peer-reviewing system to assure the quality of the publication. The Turnitin service is used to prevent plagiarism and to ensure the originality of our submitted manuscripts. Since its online publishing, ETJ has published articles in Engineering and Science disciplines. The number of issues for each discipline varied for each year. Engineering issues were recognized with the letter (A), while science issues were recognized with the letter (B). The publishing schedule was more than 12 issues per year. However, since the use of the eJournal Plus platform in August 2021, the publishing of ETJ was organized according to the subject of the articles and was set to be monthly. Therefore, an issue is published each month for a specific subject in Engineering disciplines and one issue for all Science subjects. The total number of issues is 12 issues per year.

The Engineering and Technology Journal aims to serve as a platform for Iraqi engineering and science researchers to showcase their research outputs to the global community. At the same time, it welcomes high-quality submissions from international authors, fostering a diverse and collaborative research environment.

ETJ published articles in both English and Arabic up to 2018. However, from that point onward, the journal switched to exclusively publishing articles in English. The average time from submission to first decision is 2 weeks and from submission to acceptance is 6-10 weeks depending on timely response of authors. ETJ indexed in DOAJ, COPE, CAS, Portico, CLOCKSS, Iraqi Academic Scientific Journals, and Crossref.

The migration of previously published journal issues is currently underway. In the meantime, you can temporarily access our published articles using this link.
