I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

Stephan Gauch (HU Berlin/KB) has reinterpreted the loose-leaf collection for bibliometrics, namely as a collection of short texts on core ideas of bibliometrics. It is aimed at students, practitioners and administrators, policymakers or simply anyone... Feel free to share!

Just out: Open metadata enable large-scale hybrid open access studies. Cross-database comparison using major bibliometric databases shows that transformative agreements have been the main driver of open access. But paywalls still dominate.

doi.org/10.1007/s111...
Comparison of hybrid journal indexing by data source, 2019–2023. Only hybrid journals present in the cOAlition S Transformative Agreement Data dump with at least one open access article are considered. A presents the number of journals, B the number of articles (DOI), distinguishing between shared DOI corpus and surplus in hoaddata. Box plots C shows the 5-years journal article volume (log scale). Note that intersections sets with at least 30 journals are shown

Development of open access in hybrid journals in transformative agreements by data source and author role, 2019–2023. Figure shows the open access percentage (A), the number (B) and the percentage (C) of open access articles enabled by transformative agreements.

We're excited to announce our plan to make the Royal Society journals fully open access in 2026 by adopting the ‘Subscribe to Open’ model. This change supports global access to research without shifting costs to authors and relies on continued library participation. Find out more: buff.ly/18m5g6z

I've been playing with the new Observable Notebooks 2.0 over the past days and I'm amazed. While still a preview I think it's already a serious alternative to R or Jupyter notebooks. Love that it works locally now and that notebooks are just HTML files with vanilla JS observablehq.com/notebook-kit/

I scraped unpublished manuscripts from bioarxiv and injected half of them with a hidden prompt.

I then asked three LLMs to review the paper - in half cases I told the LLM to check for prompt injections.

📈 Prompt injections lead to more recommendations

Ever wondered why no #bibliometrics lit on #German #legal #scholarship exists? Our new SSRN paper (@mpilhlt Research Paper Series 2025-10, with D. Fejzo, C. Rimmert) shows: we don't have the data. #webofscience and #scopus don't cut it, only #openalex is somewhat useful.
