World Journal of Research and Review

( A Unit of Nextgen Research Publication)

WJRR is Member of Crossref (DOI) USA

DOI: 10.31871/WJRR

Articles in online journals are mostly written by students, researchers and professors. Thousands of online Journals are published in Dongying , and many others have been published at various points in the past . Most Journals are highly specialized, although some of the oldest journals, such as WJRR, publish online articles from many fields. The journals contain articles that have been peer reviewed to ensure that the articles meet journal quality standards and scientific validity. Although online journals are seemingly similar to professional magazines, they are actually quite different.

The World Journal of Research and Review (WJRR) is a monthly peer reviewed online Journal of WJRR Publication in Dongying . WJRR publishes original research papers, case reports, research notes, short communications and review papers in science field. Authors can submit their contributions electronically through the Journal website submission system or manually by E-mail to the Editorial Office.

Author's Research Publication Tips

How much does it cost to publish a research paper?

Nowadays, journals that charge all kinds of fees are available, although publishing and promoting research papers is a social work, but nowadays many journals have made it a business. Many research journals charge 500 USD to 4000 USD fees for publishing a paper.
Getting a research paper published by paying a very high fee is not right for a student. By doing this, the student not only wastes his money but also puts his career at stake. Publishing a research paper in the true sense costs the journal a maximum of $ 100. Despite this, they earn $ 300 to $ 3,800 from students.

Is it right to publish paper in free journal?

Not in our opinion, nowadays time has become very valuable. Everybody is short on time. Free journals sometimes take up to a year to review a research paper. But if the paper is rejected after waiting for one year, then the student's entire time is wasted.
Free journals cannot do maximum indexing of your paper.
