coauthor removed other author's name after reviews I have discovered that a co-author has submitted a book chapter to a major publisher omitting my name of co-author list without me knowing. I was included in the first submissions, but corresponding author made an executive decision to not include me, based on unknown grounds. I have substantially and creatively contributed to the work, in design, datacollection and analysis. What are my options now to get credit where credit is due? technically it is plagiarism, I think.
It may or may not technically be plagiarism, but it’s definitely fraud if it was done without your consent. Papers and book chapters can be retracted for such infractions.

If this has indeed happened, then your next step—assuming you've reached an impasse with your co-authors—should be to contact the editor and publisher of the book, laying out your case with the appropriate documentary evidence included in its entirety. Make sure they have enough information that they’re not going on a “fishing expedition.” There should be clear correspondence—emails showing the work and production of the article with your participation, and so on.
