I published a paper late 2016. Recently I noticed that the published manuscript has a typo error in one of the authors affiliation. But it got indexed correctly on all databases under that author. Will it be good to contact the journal now to rectify the mistake or should I not care about that much as anyway it got indexed correctly? If I contact the journal almost after an year, will it affect the reputation of the authors? Also one of the student is going to use this paper for his PhD thesis. Considering this fact should, what is the best strategy to handle this ? Any recommendations?
