I am wondering how I can cite a preprint (likewise a working paper, or a manuscript) which I am not supposed to officially archive because of a longer double-blind review process with an anonymized version of that preprint?
Hence, this preprint is not yet assigned a DOI (like it would have been with biorXiv, arXiv, OSF, some institutional repos, etc.). However, I'd like to share it among colleagues (though, a small circle) who might want to cite it. So, I'd really like to provide them a suggestion how to cite the working paper for the time being until I can put it on arXiv (independent of whether it gets accepted or rejected in the current process).
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 Unpublished manuscript, Department of Sociology, The Top University, New York.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. Likewise, it is explained in that SE comment. However, I am not sure whether this is the standard (the best) way to do it. Has anybody a better suggestion?
