I have collaborated and written several research papers where my co-authors withheld the final draft and submitted the paper without my name as co-author. Two papers have single authors (not me) and a third paper has three authors (one of whom was not even on the research team when I conceptualised the research and analysed the data). The explanation for excluding me as author is that I did not meet the third criterion of the Vancouver protocol (final approval of the version to be published). The university supported this cheating because it follows the letter of the law. I have analysed data for a fourth paper which my collaborator has not yet published as her own. However, she is one of the single authors mentioned above, so my guess is that she will publish this as her work too. I no longer work at that department. What should I do?
I was never given a chance to review the final drafts of the manuscripts. They were submitted behind my back.
