You can send me questions for the blog using this form.

I got this question from a reader: How to import an RIS or bib-export file from Zotero (Reference Manager) and convert the data into a bibliographic class. Zotero is open access and its export cannot be read as easy as a Clavariate-bib export file. Some fields are missing, such as ID (Key in Zotero export) or CI for citations. Zotero does not extract this information and I do not need it.

The good news is that I use Zotero daily, and to answer this I will use the sub-collection I created for the Kendall’s correlation coefficient article.

After exporting that sub-collection to Zotero RDF, RIS and BIB, I realised it is not very straightforward to read this into R and export to a Clarivate-BIB file, and I had to create my own functions but those ended up being a few hundred lines and I organized those as an R package.

The code and data for this example are available on GitHub.

Install the zotero R package with:

remotes::install_github("pachadotdev/zotero")

You can see the code on GitHub and improve the functions.

Read a Zotero exported file like so:

library(zotero)
x = read_zotero("bibliography.bib")
y = read_zotero("bibliography.rdf")
z = read_zotero("bibliography.ris")

The result is the same for each object:

names(z)

[1] "df"  "bib"

z$df
