How do I cite an unpublished work in my paper? which incidentally is my second submission to the same conference The problem is I completed a work earlier and did another work which extends this work. However, I haven't got the earlier work published. I plan to send these two papers to a conference but I do not know how to cite the work of first paper in second paper.
Many people, including myself, use the following style:


  Author. “Paper Title,” manuscript, year.
  
  e.g.:
  [13] A.N. Author, “Paper Citation Rules,” manuscript, 2013.


If it's your paper you can also cite it as


  Author. “Paper Title,” submitted, year.


The proper citation style may depend on the conference you submit your paper to. In my area, theoretical computer science, there are no strict citation rules.
