Q: How do I add my name as an author to a published paper in Google Scholar?

1 Answer to this question
Answer:

Google Scholar is a search engine where one can search scholarly literature from various sources (mostly, scholarly journals). Thus, a research paper does not get “published” in Google Scholar; it is merely “indexed” there.

From your question, it appears that you want to know how your name as an author can be added to a published paper. If so, as you may know, there should be strong reasons for making the addition, and all the other coauthors should agree. If they do so, the next step would be to contact the journal editor and request that a corrigendum/erratum be published. So, to link with what we stated earlier, you cannot add your name to the paper on Google Scholar, but need to do so with the journal.
