Accepted article still not assigned a Volume or Issue number in a journal One of my research articles has been published in one of the IEEE journals. The IEEEXplore page, the data of publication is mentioned as 29 March 2016, but the article has not yet been assigned to an issue. I enquired with the concerned people and below is the reply which I got from them.


  The Editor-in-Chief of the journal determines when a
  paper is included in an issue. You can contact him directly to find
  out when he plans to publish your paper. His contact information can
  be found on Xplore. Thank you. XXXX


Should I write to the EiC about the article or should I wait till comes?
Do write, very politely, to the Editor in Chief. In most cases he just wants to pursue other topics or maybe wants to bundle your work with a similar one which is not yet 100% ready.

Rarely, though, even editors might make mistakes, and it is not impossible that your work had been involuntarily shelved.
