I like Google Scholar's alert feature, where you can subscribe to alerts about an author's new publications.
However today I found out this feature is limited to 200 alerts. After that, I cannot follow any more authors. (Ref. How to increase the number of authors followed in Google Scholar?).
Thus, is there any alternative service that tracks the publications of an author as well as Google Scholar? I have tried Semantic Scholar, but I find it a bit lacking (e.g., often an author will appear with multiple profiles with slight name variations). Any other suggestions?
