refsplitr 1.2.3 (2026-06-16)

authors_clean() would sometimes combine authors with very similar or identical names in the same groupID even if they had different ORCID ID numbers. A tweak in authors_match() now eliminates these ‘false positives’.

modified the section of authors_parse() that identifies corresponding author and reprint address (RP field code). There are cases where there is more than one corresponding author, with names separated by a ‘;’. This was causing both authors to be ignored. The revision treats only the first name provided as the corresponding author.
email matching with author names improved. It previously compared similarity of author name fields (AF and AU) with emails to match them with jarow-winkler. However, this was reducing the likelihood of a match because (1) AU is in format “last, first”, but emails don’t have commas or spaces which was slightly penalizing the match and (2) j-w matching favors with the same initial characters, but emails are often in reverse order, e.g., AF = “last, first”, while email = “first.last@…”. Now compares AU and AF after commas and spaces are removed and uses Jaccard to compare the strings to allow for reverse order of names in emails and AF/AU fields.
WOS records have (rare) errors as follows in the OI field : “Lastname, Firstname / Firstname/0000-0003-0000-3152” instead of the correct: “Lastname, Firstname/0000-0003-0000-3152”. This was causing OIs to be deleted from an authorID. Added a function to check for these errors and correct them.

corrected an error in authors_address() that was changing “USA” to “NA” when parsing countries.

The new default service for georeferencing author institutions is the free Nominatim service, which uses OpenStreetMap (OSM) data and which refsplitr queries via the [tidygeocoder]((https://jessecambon.github.io/tidygeocoder/) package.tidygeocoder. The Google Maps API is still an option, but users should be aware that their georeferencing request may exceed the lower limit of free queries.
The authors_addresses() function has been updated and is now more efficient.
In plot_net_address(): the deprecated function fortify has been replaced with sf_convert

references_read() now extracts additional fields from Web of Science records: WE (Source Database), C3 (all author affiliations, equivalent to the Scopus affiliations field code), EI (eISSN), OA (Open Access), and RID (the original version of the Thomson-Reuters ResearcherID (RI); authors of some older publications might have an RID but not an RI). These are not included in the default output of references_read(); to include them use include_all = TRUE.
references_read() no longer extracts some rarely used field codes: GE, LT, MC, MI, and TA
The following field codes are now returned by default when using references_read(): DT (Document Type), ID (Keywords Plus), IS (Issue), JI (ISO abbreviated source code), and NR (number of references cited by the article).
corrected a bug that was

output of plot_net_country() now includes a list of any authors that have a lat-lon but no country (called with products$fixable_countries()).Users can correct these and re-run the visualization to include them in the graph.
