How I can cite a submitted manuscript which I am not supposed to publicly archive (e.g. on arXiv) because the review process is double-blind (i.e. the manuscript is anonymized and should not be archived in a way that reveals authors' identities) and/or the journal has a restrictive archival policy?
This manuscript may therefore not be assigned a permanent link (like it would have been with biorXiv, arXiv, OSF, some institutional repos, etc.). I am aware of platforms such as Zenodo allowing anonymous archival but these do not necessarily imply a citation format to be used. However, I'd like to share the manuscript among colleagues who might want to refer to it. So, I want to suggest to them a citation format while it's under review.
I found this, suggesting me to do that:
Doe, J., & Smith, A. (2012). A study on the difficulty of getting manuscripts published. Unpublished manuscript, Department of Sociology, The Top University, New York.
where manuscript can be substituted by something like working paper or preprint. See also that SE comment. However, I am not sure whether this is the best way to do it. Any better suggestions?
