Citing papers that use unpublished data that I want to publish I am getting ready to submit a method paper which describes a dataset that I had created. However, I was late getting the paper ready, and a couple of other colleagues used the dataset in their own papers, and those papers are already online (I am coauthor in them).

The other papers do not describe in detail how the dataset was constructed. I am afraid that if cite them, it might harm my chances of getting my own paper on the dataset published. Any suggestions on what would be the right thing to do?

thanks!
If you have at least 40 % new material you can submit your paper to journals and you should also cite the other paper without any hesitation.
