At TimeLine Journals, we understand that some institutions may have limited funding for their research activities. Thus, we have instituted a generous waiver system that may ease the payment of the manuscript handling fee when their researchers choose to publish their manuscripts in any of our journals. Our primary goal as stated in our mission is to accelerate the dissemination of knowledge through the publication of high quality research articles. We are continually pursuing this goal, without putting undue financial burden on researchers or their institutions. Hence, we have instituted the following waiver policy.
Authors from Low Income Countries may be granted up to 75% waiver.
In addition, it is also not unusual for authors to be granted full waivers, especially authors from low income countries.
To request a waiver, kindly send an application on concern journal email. Waiver application should contain the manuscript number and state the reason for requesting a waiver.
