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 ?
