The specific paper I'm interested in is Galton (1907), and one approach I worked out is to go to Galton's Google Scholar profile and then click on the paper in question, after which I can see the following histogram:
This is the kind of thing I want to create, but one problem is that it cuts off in 2005.
If I click on the article itself and look within citing articles I can see there are several citations before 2005, but it wasn't apparent to me that there was a way to count them without manually going through each page.
Is there a way for me to obtain data for the number of citations by year (including pre-2005) without manually going through the citing articles?
