Existing publication in Google Scholar profile vanished During January 2017 I noticed that one of my publications from 2000 that had a significant number of citations had disappeared from my Google Scholar publication list. I re-entered the missing publication manually, however, the citations have not reappeared. Rather another author’s paper appeared in my publication list with several hundred citations. I noticed the same problem in a colleague’s Google Scholar publication list. 

Any suggestions to resolve the issue would be appreciated.
There is nothing much to do except for things which you already did and can try again:


Add/remove the publication manually
Submit a request for correction
Contact Google Scholar directly for help about this specific problem (https://support.google.com/scholar/contact/general)


The Scholar system is highly automated, and their automatic methods for parsing/counting of citations can change abruptly and cause general fluctuations in the level of citation. I have noticed it is quite common to see my citation count suddenly increase or decrease by as much as 100 citations (and in one case it changed by more than 500).

Alternatively you can use other citation count resources such as Web of Science or Scopus.
