Get the citation count for the a publication for a particular period #210

Open shaniAmare opened 3 years ago

Hi @cboettig and @sckott,

Sorry for the naive question.

I am using the rcrossref package for a database I am developing. I was wondering whether there is any way that I can, for a publication, get the citation count for a particular year only? Say, for example, a particular DOI, get the number of citations for the year 2020 only?

I looked around but I couldn’t find an answer to this anywhere.

Many thanks in advance! Shani.

Thanks for your question. To clarify, I assume you mean count of papers citing paper X, vs. the number of references paper X cites?

If the former, and the one most people want, that's generally heavily protected data by publishers as they think its a business advantage for them not to share it.

You may be able to get it via Scopus or WOS if you have access to those. We have the function here cr_citation_count but that gets total citation count

Another option might be http://opencitations.net/ which we have an R package for https://github.com/ropensci/citecorp , e.g., you could do 

library(citecorp)
z <- oc_coci_cites("10.1108/jd-12-2013-0166")
head(z)

And then construct citation counts by year yourself. This of course would only work for the DOIs open citations has data for.
