I was immensely saddened to learn of the recent passing of Bart van Tiggelen.

He was a great researcher, a wonderful human being, and an engaged scientist with his heart in the right place. I will miss our inspiring and (re)motivating conversations.

Hommage à Bart van Tiggelen, 1965-2025

C’est avec une grande tristesse que les membres de la société française de physique ont appris la disparition de Bart van Tiggelen, le 20 décembre 2025.

@jscaux thanks for sharing Jean-Sébastien!

Feel very seen by this comment rn
> failed funding applications however have very real consequences for real people employed by initiatives actually doing open science on the ground

Congratulations to the 45 grantees of the @OpenScienceNL infrastructure round! With 35M euros allocated, this is major news.

This post is however reaching out to candidate individuals and teams who did *not* submit to the final (second) round after submitting a preproposal.

Mastodon hive mind, can you help me trace them? I'd like to hear about those projects.

I have some thoughts on how allocation of resources to open science initiatives could be improved. https://jscaux.org/blog/post/2025/12/18/open-science-nl-art-of-retrospective-duping/

Jean-Sébastien Caux: blogpost on Open Science NL and the art of retrospective duping

In recent years, #SciPost has grown into an essential open science infrastructure.

Our sustainability is however under threat.

Only 147 out of 1351 (a mere 11%) benefitting organizations have supported us.

This ongoing level of freeriding means we are now at a crossroads.

Academic organizations urgently need to change tack and fulfil their promise to sustainably support scientists-led, not-for-profit publishing infrastructure.

Help us convince them to support us.

Jean-Sébastien Caux: blogpost on SciPost at a crossroads

How can we inoculate academic publishing against bad business practices?

How can we build a more affordable and equitable system, for the sake of academia?

Like this: https://scipost.org/finances/business_model/

Look into it.
Let others know about it.
Help us build it.

SciPost: Business Model

SciPost Business Model

The Principles of Open Scholarly Infrastructure embody a set of guidelines through which research community-serving organizations can be operated and sustained.

As part of our #SustainOurServices campaign, we have published a detailed self-audit describing the relevance and implementation status of these principles.

The situation is very good to excellent on the governance and insurance side, but some aspects of the sustainability side need urgent attention.

SciPost: POSI

SciPost POSI

I don't want to offend anybody, but I think there is a need for more honesty regarding how it's all going with the reform of publishing.

I think it's not going well.

There is so much more good that could happen so rapidly. Instead, reform seems to be stuck in an illusory "tragedy of the commons", while a very real "treachery of the private" is happening. Academia is manifestly being outsmarted by corporate-directed forces.

I'd love to be proved wrong.

Jean-Sébastien Caux: blogpost on Being honest about the reform of publishing

Today we are launching SciPost's Sustain Our Services Campaign.

This campaign has the following primary objectives: to ensure continuity of support for our services; to engage organizations which have benefitted from our activities, but not yet supported us; to reduce our financial uncertainty; to empower our growth and widen the positive impact we have.

We look forward to engaging with you during the course of this campaign!

SciPost: News Item

We've just published a post on our blog https://scipost.org/blog/, looking back at our operations in 2023.

2023 saw us publish 748 papers, with a unit average expenditure of €495.

We grew our team to keep up with increasing demand on our Genuine Open Access services; though this reduced backlogs, it depleted our financial reserves. Our growth is stunted and our long-term financial sustainability remains a distant perspective due to challenges in gathering support.

Our mission is far from over!
