Collection of books seen from above

Matilda has reached 160M deduplicated publications, among which 33M are full-text searchable. Everything is free, sharable and reusable and will remain as such under our #POSI commitments and following our mission matilda.science/mission?l=en

Matilda has adopted the Principle of Scholarly Infrastructure (POSI). For full details, see here #OpenScience matilda.science/posi?l=en

📣 Our introduction to structural causal models in science studies is now published:
doi.org/10.1162/QSS....

@tklebel.bsky.social and I tried to make our introduction as accessible as possible. We illustrate the theory by three case studies based on a simulated model of Open Science. 🧵(1/6)

Our monthly review of the coverage of the major bibliographic databases (January 2026).
We excluded Xueshu Baidu and FatCat and duplicated the OpenAlex info and added PubMed, a relevant IA source

Matilda academic search engine – Get this Extension for 🦊 Firefox (en-US) Download Matilda academic search engine for Firefox. Adds the Matilda.science academic search engine to your search bar

For Firefox users, I also wrote a small add-on that allows you to search Matilda directly from the search bar. (Not officially endorsed by the great people at @matilda-science.bsky.social)

The image shows the uptake in matilda.science objects : +15M works, +20M full-text search, +1.1M recognized authors +600M citation links

The power of #opendata, automation, @foxcubfr.bsky.social maintenance and Huma-Num services. In 2026, so many new objects are searchable on matilda.science?l=en #discover #openscience @cnrs-inist.bsky.social

If you wish to study how editors wish Happy new year to their readers and authors, you will find hundreds of them in Matilda. #opendata #discoveryservice matilda.science/search/?l=fr...

At Matilda, we don't use affiliation data, but we have developed a multi-source pipeline to avoid such data capture. In order to achieve @barcelonadori.bsky.social goals, we need to outweigh those who see this data produced by researchers as an asset to be enclosed. #openscience

Yes indeed. We have a world wide basis (Crossref, PubMed, RePEc, ArXiv), but as we include HAL, most French-affiliated research can be found and followed (alerts, citation tracking...). Any comments very welcome

In one sentence: OpenAlex is made to count (bibliometrics, scientometrics), Matilda is made to read (bibliographical tools).

An example of search query in Matilda, if you work on research assessment reform like @coarassessment.bsky.social, here on Narrative CV in English, French, German, Spanish #openscience #opendata matilda.science/search/?l=fr...

The harshness of grant calls in the research world: our project received the maximum grade of 100/100... and still was not funded.

Is there a relationship between the metadata publishers submit to Crossref and the submission systems they use? 🤔

We (w/ @msphelps.bsky.social) analyzed 153 publishers and 4 major systems to find out.

#OpenScience #Crossref #OpenMetadata #BarcelonaDeclaration

That is why we have multiple sources in Matilda and deduplicate to get abstracts and, more importantly, full-text indexing to achieve maximum discoverability. #openscience #openresearchinformation

Today on the blog, we feature Matilda, a bibliographic platform built specifically for open science. We spoke with project lead Didier Torny about the project, and their plans to incorporate links to datasets for the articles they index in Matilda.

We will never have any AI (LLM) component inside Matilda to avoid that situation. Bibliographic search needs deterministic, transparent and reproducible processes. AI-training robots already come to the platform, which is fine, though we need to slow them down to avoid DDOS-style crashes.

Tonight at #OSFair2025 we perform two Matilda demos. Come and let's chat around #openscience in bibliographic search www.opensciencefair.eu/demos/matild...

The underlying architecture enables it, so at least we will give it a try... if we get the funds (3 calls pending...)

Thanks. In further developments, we wish to use our property graph to actually link these reviews to "their" article, but also book reviews to actual books. Probably tricky at full scale but that would be the goal.

You can now download the book on the publisher's website: press.umich.edu/Books/P/Publ... (open access of course)

A remarkable colleague, whose work is the reason why we chose "Matilda" for our open bibliographical platform. Read not only her "Matilda effect" article, but her extensive work on the history of women in science. #STS #historyofscience

Matilda is LLM-free so that you can always trace back any data/reference/publication to trusted sources. Of course we don't build fancy bios, we just give you the link to the author's ORCID page #openscience #opendata

Not sure how many scientists here have tried Claude Code or similar command line coding assistants. I had a complicated family property tax problem that was best solved by a brute force Monte Carlo simulation approach, so I spent a few days coding up and analyzing a model with Claude Code.

The beauty of full-text search in Matilda. Among 27M papers, at least 61 use "herbal language" (instead of natural language). #openscience #researchintegrity matilda.science/search/?l=fr...

Another manuscript with authors but not readers. Who can approve "herbal language" and "face popularity" in a paper? How can IEEE not be fined for fraud and boycotted by institutions and authors? #researchintegrity #openscience

Matilda.science hits new milestones!
151.3 M works, 254.5 M texts, 12.3 M authors, all connected in an ever-growing research graph.

Citations in the graph: 174.6 M total, 41.1 M from full texts.

And we’re still growing!

#OpenScience #FAIRData @matilda-science.bsky.social @foxcubfr.bsky.social

We keep on growing, and that includes 26M publications with full-text search. No ID needed, everything is reusable and shareable #openscience #opendata

My PhD candidate Juan Pablo Bascur submitted one of his papers to MetaROR. The reviews of his paper have now been published on the platform.

Very glad to see early-career researchers embracing new approaches to scientific publishing!

Matilda has just passed two milestones: 150M different works are included and you can full-text search 25 millions of them We aim at 200M and 50M a year from now. matilda.science?l=en #scientificpublishing #opendata
