Checking whether you have cited some other researcher Sometimes you need to find out quickly whether one of your papers has cited a particular researcher given only the name of that researcher. Is there a tool for that? Assume you have used the bibtex format so far to manage your references, but your bibtex files contain much more than what you've actually cited.  You have no Zotero or Mendely and don't want to mess with them unless really necessary. You have your own webpage with lots of paper copies, and you have profiles at Google Scholar, ResearcherId, and Orcid.

Google Scholar and ResearcherID can tell you who cites you. As opposed to that, you wish to determine whether you cite someone else (or not).  To start with, a binary answer (yes/no) would do.  You would like to run such a query several times, one researcher at a time. Ideally, the query would give you some (or even all) of your papers which cite the given researcher, but it's not a must. 

Surely you can do that by putting all your texts together, converting them all to text or html, and then searching there. This is tedious and error-prone, though. Is there any online (or offline) service for that, perhaps? The database in which the search is done must be a (possibly large) underapproximation of the papers you have written so far.
If you are fine with looking at only Web of Science indexed articles then yes, this is easily possible using Web of Science.


Do a "Cited Reference Search" and search for the name of the researcher you are interested in
Select the publication of that researcher and hit "Finish Search", you now end up with a list of every paper citing the previously selected papers of that researcher
Do a basic author search of your own name, you end up with a list of your own papers.
Go to "Search History" and select these two searches and combine the two sets with the "AND" operator.


There's another way to do this using Web of Science. It will take some time and work to set up (depending on how many publications you have) but the process of checking can be automated afterwards. You have to create a list of all papers you cited which includes the author names of the cited papers.


Search for your publications on Web of science
For each publication open the details, on the right it shows the number of "Cited references", click on that number you end up with a list of papers you cited
Export this list to endnote (you have to do this for every page)
Eliminate duplicates in Endnote.


You now have an Endnote database with all the publications you cited which can easily be searched for authors.
