Is there a simple way to see how many times a scientific book has been cited? And who cited it?
If the book has been listed on ResearchGate, you will usually get this information as part of whatever aggregation process they do behind-the-scenes (assuming also that the citers/citees are in the same databases).
You can do the same thing by entering your book into Google Scholar. Since the databases are different, the results will undoubtedly differ as well.
Separate names with a comma.
