Which publication information should be mentioned in CV : Online first, or volume(issue)? One of my research work was published in the year 2015 as Online First article and has also received a few citations.

Just recently, it got published in the formal Volume (Issue), pp. 1234 -- 1250, 2017.

I had listed this publication as 2015, (In press) till now. But, I am now confused, whether should I remove the year 2015 completely from my CV, or should I keep both like (Online first, 2015), Volume (Issue), pp. 1234 -- 1250, 2017 ?
It's really up to you how you list your references, what I do is to list it with the updated information on the CV, due to:


This reflects the actual state of the article which will come up in searches.
The later date of the full publication shows that the article is one of the 'latest' in the field.
The article often has the published online date anyway, alongside the other important dates, at the beginning of the article.


I have always taken the CV as being a way of 'showcasing' the latest state of the researcher's work.
