Hello Folks,
How are you doing today? Me? reviewing a manuscript. This manuscript is prepared by prominent research scientists. Disapointed seeing 80 % of content including figures have been copied from a previously published manuscript by the same authors. Google search establishes that two of their papers have been retracted.
Is it normal for an author to copy 70 - 90 % content from their previously published paper and submit it as a new manuscript? What course of action should we be taking now? Thanks.
