How to find scientists that cited several of my papers? There are several ways to find online scientists that cited one of your papers (Google Scholar, PubMed, Web of Science, etc). Recently, however, I ran into a scenario in which I wanted to find authors that cited a specific subset of my papers. To clarify, I don't mean that these citations have to be in the same paper - they could be in different papers by the same author.

One option would be to export the citation data for each of my papers and write some script that parses and extracts the answer. Does anyone know of a simpler/online method of doing this sort of complex query?
You need to first get a database put together of all those who potentially might have cited your work, and the bibliography of their papers.  This is not trivial, esp. if you are in a field where you don't have pre-existing online citation databases for published works.

Are your works available in such a format?  If so, then just do a query which you think will capture all the related papers to your work.  If you are cited in MEDLINE, you can use the "paper like this" as well as exploded MeSH based searches.  Start with the MeSH terms assigned to your work, and spend a little time going over where those show up in the MeSH hierarchy.

Also, how are you defining a specific subset of your papers?  Is this something you know a priori or are you expecting that subsets fall out based on who cited your work?

If your subset is small, and/or you don't have many citing authors, this would  be quicker to just do by hand.  Just build a bibliography from those who cited you (e.g. export Google Scholar/MEDLINE entries, which will have all the authors), and you can then parse that (download them in an XML format and you can probably use XPath/XQuery to do what you need, or see of one of Zotero's report options will help).
