Weekly Update from the Open Journal of Astrophysics – 09/05/2026

It’s Saturday once again, so time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further five papers, bringing the number in Volume 9 (2026) to 99 and the total so far published by OJAp up to 547. We didn’t quite make it to a hundred for the year last week, but will do so with the next paper.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.

The first paper to report this week is “Formation of Close Binaries through Massive Black Hole Perturbations and Chaotic Tides” by Howard Hao-Tse Huang and Wenbin Lu (University of California at Berkeley, USA). This one was published on Wednesday 6th May 2026 in the folder Astrophysics of Galaxies. The paper presents a model of massive black hole-binary systems, showing that repeated tidal interactions can lead to the creation of hyper-velocity stars and other nuclear transients.

The second paper for this week, also Wednesday 6th May, but in the folder Cosmology and Nongalactic Astrophysics is “Detection of supernova magnitude fluctuations induced by large-scale structure” by Andrew Nguyen (Swinburne Institute of Technology, Australia) and 58 others based all around the world. This study uses supernovae and galaxy velocities to measure the universe’s structure growth rate, confirming the Planck LambdaCDM model prediction. The methodology is validated and shows potential for future research.

Weekly Update from the Open Journal of Astrophysics – 18/04/2026

It is Saturday morning, and therefore time for yet another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further six papers, bringing the number in Volume 9 (2026) to 82 and the total so far published by OJAp up to 530.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.

The first paper to report this week is “Beyond Spherical geometry: Unraveling complex features of objects orbiting around stars from its transit light curve using deep learning” by Ushasi Bhowmick & Shivam Kumaran (Indian Space Research Institute, Ahmedabad, India). This study uses deep neural networks to predict the shape of objects orbiting stars based on their transit light curves, demonstrating the potential to extract geometric information from these systems. It was published on Monday 13th April in the folder Earth and Planetary Astrophysics and the overlay can be seen here:

Weekly Update from the Open Journal of Astrophysics – 11/04/2026

With permission, I have time for yet another Saturday morning update of activity at the Open Journal of Astrophysics. Since the last update we have published a further five papers, bringing the number in Volume 9 (2026) to 76 and the total so far published by OJAp up to 524.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter (which nobody should be using); these announcements also show the DOI for each paper.

The first paper to report this week is “Lagrangian versus Eulerian Methods for Toroidally-Magnetized Isothermal Disks” by Yashvardhan Tomar and Philip F. Hopkins (California Institute of Technology, USA). This study re-evaluates previous research on toroidally-magnetized disks, using two Lagrangian methods. The results suggest that sustained midplane toroidal fields in recent simulations are not a numerical artefact. It was published on Tuesday April 7th 2026 in the folder High-Energy Astrophysical Phenomena.

The second paper for this week, published on Wednesday 8th Apil in the folder Instrumentation and Methods for Astrophysics, is “Teaching Astronomy with Large Language Models” by Yuan-Sen Ting and Teaghan O’Briain (Ohio State University, USA). The paper introduces AstroTutor, an AI-enhanced astronomy tutoring system, to improve undergraduate astronomy education and AI literacy. It found that structured AI integration can enhance learning and critical evaluation skills. The primary classification on arXiv for this paper is physics.ed-ph but it is cross-listed on astro-ph which qualifies it for consideration.

Weekly Update from the Open Journal of Astrophysics – 07/02/2026

It’s Saturday once more so time for another update of activity at the Open Journal of Astrophysics. Since the last update we have published a further six papers, bringing the number in Volume 9 (2026) to 24 and the total so far published by OJAp up to 472.

I will continue to include the posts made on our Mastodon account (on Fediscience) to encourage you to visit it. Mastodon is a really excellent service, and a more than adequate replacement for X/Twitter which nobody should be using; these announcement also show the DOI for each paper.

The first paper to report this week is “The Impact of Star Formation and Feedback Recipes on the Stellar Mass and Interstellar Medium of High-Redshift Galaxies” by Harley Katz (U. Chicago, USA), Martin P. Rey (U. Oxford, UK), Corentin Cadiou (Lund U., Sweden) Taysun Kimm (Yonsei U., Korea) and Oscar Agertz (Lund). This paper was published on Monday 2nd February 2026 in the folder Astrophysics of Galaxies.

Gemeinsam Open-Access-Infrastruktur stärken: Konsortium „PKP Open Journal Systems Deutschland 2026–2028“ mit 14 deutschen Einrichtungen gestartet

Im Januar 2026 startet das neue Konsortium „PKP Open Journal Systems Deutschland 2026–2028“. 14 Einrichtungen aus Deutschland haben gemeinsam ihre Unterstützung für das Public Knowledge Project (PKP) erklärt und sich für die nächsten drei Jahre zu Mitgliedsbeiträgen verpflichtet. Auf diese Weise tragen sie zur nachhaltigen und gemeinsamen Finanzierung relevanter Open-Access-Infrastruktur bei.

Im Herbst 2025 haben PKP und TIB wissenschaftliche Einrichtungen in Deutschland aufgerufen, diesem Konsortium beizutreten. Open Journal Systems (OJS) ist die weltweit am weitesten verbreitete offene Software für wissenschaftliches Publizieren. Sie ist eine wesentliche Voraussetzung für zahlreiche wissenschaftsgetragene Publikationsangebote in Deutschland und ermöglicht auf diese Weise eine sehr große Anzahl an Diamond-Open-Access-Publikationen. Ziel des Konsortiums ist es, die Entwicklung dieser Software sowie weitere relevante Aktivitäten von PKP abzusichern.

Zum Start haben diese Einrichtungen ihren Beitritt erklärt:

• BIS – Bibliotheks- und Informationssystem der Universität Oldenburg
• Hochschulbibliothekszentrum des Landes NRW
• Humboldt-Universität zu Berlin – Universitätsbibliothek
• Technische Informationsbibliothek (TIB). Leibniz-Informationszentrum Technik und Naturwissenschaften und Universitätsbibliothek
• Universität Heidelberg – Universitätsbibliothek
• Universität Konstanz, Kommunikations-, Informations-, Medienzentrum (KIM) IT- und Bibliotheksdienste
• Universitäts- und Stadtbibliothek Köln
• Universitätsbibliothek Braunschweig
• Universitätsbibliothek Clausthal
• Universitätsbibliothek der Technischen Universität Berlin
• Universitätsbibliothek Koblenz
• Universitätsbibliothek Leipzig
• Universitätsbibliothek Mannheim
• Universitätsbibliothek Potsdam

Update April 2026:

Zusätzlich sind mittlerweile beigetreten:

• Sächsische Landesbibliothek – Staats- und Universitätsbibliothek (SLUB)
• Universitätsbibliothek der LMU München

Ende Update

Alle teilnehmenden Einrichtungen werden eigenständige PKP-Mitglieder und können sich in die PKP-Community und -Diskussionen einbringen. Die TIB hat die Vereinbarung organisiert, kümmert sich um die regelmäßige Informationsversorgung der Konsorten und ermöglicht deutschen Einrichtungen, ihre Beiträge in stabiler Höhe und in Euro an die TIB zu entrichten.

In den aktuellen Diskussionen um Open-Access-Infrastrukturen gibt es viele Appelle für den Betrieb wissenschaftsgetragener Publikationsangebote. Gleichzeitig gibt es wenig Ansätze für eine breit getragene und damit sicherere Finanzierung solcher Infrastruktur. Mit dem neuen Konsortium schaffen wir eine gute Möglichkeit für Einrichtungen, möglichst einfach zu unterstützen. Der Beitritt zum Konsortium ist weiterhin möglich. Wir freuen uns auf weitere Mitglieder.

Wir bedanken uns bei PKP und allen Mitgliedern dieses neuen Konsortiums. Unser gemeinsamer Einsatz kommt nicht nur unseren eigenen Einrichtungen zu Gute, sondern hilft dem Open-Access-Publizieren deutschlandweit und international. Damit leistet es auch einen Beitrag zur besseren Informationsversorgung deutscher Forschungseinrichtungen.

Lesen Sie auch die PKP-Nachricht zum Start des Konsortiums.

Strengthening open access infrastructure together: “PKP Open Journal Systems Germany 2026–2028” launched with 14 German academic institutions

In January 2026, the new consortium “PKP Open Journal Systems Deutschland 2026–2028” has been launched. 14 institutions from Germany have jointly declared their support for the Public Knowledge Project (PKP) and committed to membership fees for the next three years. In this way, they are contributing to the sustainable and joint financing of relevant open-access infrastructure.

In autumn 2025, PKP and TIB called on academic organisations in Germany to join this initiative. Open Journal Systems (OJS)is the world’s most widely used software for scholarly publishing. It is an essential prerequisite for numerous academia-owned publishing services in Germany and thus enables a very large number of diamond open access publications. The consortium’s goal is to secure the development of this software and other relevant activities of PKP.

The following institutions have declared their membership at the outset:

• BIS – Bibliotheks- und Informationssystem der Universität Oldenburg
• Hochschulbibliothekszentrum des Landes NRW
• Humboldt-Universität zu Berlin – Universitätsbibliothek
• Technische Informationsbibliothek (TIB). Leibniz-Informationszentrum Technik und Naturwissenschaften und Universitätsbibliothek
• Universität Heidelberg – Universitätsbibliothek
• Universität Konstanz, Kommunikations-, Informations-, Medienzentrum (KIM) IT- und Bibliotheksdienste
• Universitäts- und Stadtbibliothek Köln
• Universitätsbibliothek Braunschweig
• Universitätsbibliothek Clausthal
• Universitätsbibliothek der Technischen Universität Berlin
• Universitätsbibliothek Koblenz
• Universitätsbibliothek Leipzig
• Universitätsbibliothek Mannheim
• Universitätsbibliothek Potsdam

Update April 2026

In the meantime, these institutions have joined the consortium:

• Sächsische Landesbibliothek – Staats- und Universitätsbibliothek (SLUB)
• Universitätsbibliothek der LMU München

End of update

All participating institutions become PKP members and can contribute to the PKP community and discussions. TIB organised the agreement, takes care of providing regular information to the consortium members, and enables German institutions to pay their contributions to TIB in a stable amount and in EUR.

In the current discussions about open access infrastructures, there are many calls for the operation of scholar-led, academia-owned publishing services. At the same time, there are few approaches for broadly supported and thus more secure financing of such infrastructure. With the new consortium, we are creating a good opportunity for institutions to provide support as easily as possible. It is still possible to join the consortium. We look forward to welcoming new members.

We would like to thank PKP and all members of this new consortium. Our joint efforts not only benefit our own institutions, but also help open access publishing throughout Germany and internationally. In this way, it also contributes to improving the supply of information to German academic institutions.

See PKP’s post about the start of the consortium.

Fans of open access, unite: you have nothing to lose but your chained libraries

When books were rare and extremely expensive, they were often chained to the bookcase to prevent people walking off with them, in what were known as “chained libraries”. Copyright serves a similar purpose today, even though, thanks to the miracle of perfect, zero-cost digital copies, it is possible simultaneously to take an ebook home and yet leave the original behind.

Stärkung offener wissenschaftlicher Infrastruktur: PKP Open Journal Systems Deutschland 2026–2028

read this article in English

Aufbauend auf der langjährigen Zusammenarbeit der TIB mit dem Public Knowledge Project (PKP) wurde ein neues Konsortium gebildet, um die Aufgaben von PKP zu unterstützen: die Zusammenarbeit mit einer globalen Gemeinschaft zur Entwicklung von forschungsbasierter, freier und quelloffener Software und zur Verbesserung der Qualität, Vielfalt und Zugänglichkeit wissenschaftlicher Veröffentlichungen. TIB und PKP bitten akademische Organisationen aus Deutschland, Mitglieder dieses Konsortiums zu werden.

Unterstützen Sie OJS gemeinsam, indem Sie PKP-Mitglied werden

Open Journal Systems (OJS) ist die weltweit am weitesten verbreitete offene Infrastruktur für wissenschaftliches Publizieren. Seine Entwicklung bleibt ein Kernstück der Aktivitäten des Public Knowledge Project (PKP). Als ein Projekt zur Entwickung freier Software und zur Durchführung von Forschung ermöglicht PKP das Open-Access-Publizieren ohne Lizenzkosten und ist nicht von kommerziellen Verlagen abhängig.

Auch freie Software braucht zuverlässige Unterstützung. Mit der Unterstützung einer großen und aktiven Gemeinschaft pflegt und entwickelt PKP die Software kontinuierlich weiter. Eine stabile finanzielle Basis ermöglicht es PKP, diese wichtige Arbeit fortzusetzen.

PKP wird von institutionellen Mitgliedern – Universitäten und anderen Organisationen, die einen jährlichen Mitgliedsbeitrag leisten – finanziell unterstützt. Ein neues Konsortium, PKP Open Journal Systems Deutschland 2026–2028, wurde gegründet, um die Mitgliedschaft für die deutsche wissenschaftliche Einrichtungen zu erleichtern.

Ein nationales Konsortium zur Unterstützung einer internationalen offenen Infrastruktur

Diese neue Initiative steht nun allen öffentlich finanzierten deutschen Universitäten und Forschungseinrichtungen offen. Über das Konsortium können Organisationen über eine deutsche Infrastruktur Mitglied von PKP werden – in Euro, mit klaren Prozessen und minimalem Verwaltungsaufwand. Die TIB leitet dann die Mitgliedsbeiträge an PKP weiter. Zusammen mit den Beiträgen von Mitgliedern aus der ganzen Welt fließt diese Unterstützung in die Arbeit von PKP und ermöglicht die Weiterentwicklung von OJS und der übrigen Software-Suite von PKP (d.h. OMP und OPS).

Dieses Konsortium ist ein gutes Beispiel für die Vorteile, die sich aus dem verteilten und doch miteinander verbundenen PKP-Netzwerk von Zeitschriften, Institutionen und Communities ergeben. Die TIB ist ideal positioniert, um dieses Vorhaben zu organisieren, nicht nur als langjährige Nutzerin der PKP-Software, sondern auch dank ihrer umfangreichen Erfahrung in der Verwaltung und Koordinierung von Konsortialvereinbarungen.

Warum ein Beitritt zum Konsortium sinnvoll ist

• Sicherstellung der langfristigen Nachhaltigkeit: Ihr Beitrag an PKP trägt dazu bei, die kontinuierliche Weiterentwicklung von OJS, OMP und OPS zu gewährleisten und damit eine wichtige Open-Access-Infrastruktur zu sichern. Mehr als die Hälfte aller Diamond-Open- Access-Zeitschriften verwenden OJS. Indem Sie PKP unterstützen, tragen Sie dazu bei, ein System aufrechtzuerhalten, das Forschenden kostenlose, qualitativ hochwertige Wissenschaftsergebnisse zur Verfügung stellt.
• Investition in eine kosteneffiziente und verantwortungsvolle Infrastruktur: Ihre Institution profitiert bereits davon, dass OJS frei verfügbar ist. Wenn Sie OJS hosten – z.B. für einen Universitätsverlag – müssen Sie keine Lizenzgebühren zahlen. Ihre Forschenden veröffentlichen in OJS-gestützten Zeitschriften auf der ganzen Welt, von denen fast alle keine Gebühren verlangen, auch weil sie selbst keine Lizenzgebühren zahlen.
• PKP-Mitgliedschaft: Ihre Einrichtung wird ein eigenständiges PKP-Mitglied und genießt alle Vorteile der Mitgliedschaft. Ihre Mitgliedschaft wird auf der PKP-Website gewürdigt.
• Einfacher Weg zur Mitgliedschaft: Wenn Sie dem Konsortium beitreten, können Sie über ein deutsches Mitgliedschaftsmodell ganz einfach Mitglied von PKP werden. Die TIB hilft Ihnen gerne bei Ihren Fragen.
• Stabile Kosten in Euro: Die Mitgliedsbeiträge werden von der TIB in Euro, nicht in kanadischen Dollar, erhoben und gelten für die gesamte Laufzeit des Vertrags (2026–2028)
• Information und Vernetzung: Sie erhalten Informationen über die Aktivitäten von PKP und können an Mitglieder- und Communityveranstaltungen teilnehmen. Die TIB wird ein jährliches Treffen des Konsortiums organisieren, um die Bedürfnisse der Community zu koordinieren und über die Entwicklungen bei PKP zu informieren, in der Regel unter Beteiligung von Vertreter:innen von PKP. Die Mitglieder des Konsortiums erhalten außerdem regelmäßig digitale Updates zu den aktuellen Aktivitäten von PKP, einschließlich der Softwareentwicklung.

Gemeinsame Verantwortung

Die PKP-Software und -Dienste sind ein zentrales und entscheidendes Element der deutschen und internationalen Open-Access-Landschaft. Open Journal Systems macht die große Mehrheit aller Diamond-Open-Access-Zeitschriften aus. Ohne eine breite Beteiligung von Institutionen, die von OJS profitieren, ist seine weitere Entwicklung unnötig gefährdet. Das deutsche Konsortium bietet einen klaren und praktischen Weg, gemeinsame Verantwortung zu übernehmen – mit sichtbaren Vorteilen für alle beteiligten Organisationen.

Informationen zum Beitritt

Das Konsortium ist daran interessiert, so viele öffentlich finanzierte akademische Einrichtungen aus Deutschland wie möglich als Mitglieder zu gewinnen. Wenn Sie an einer Teilnahme interessiert sind, übermitteln Sie bitte Ihre Daten mit diesem Formular:

Strengthening open scholarly infrastructure: PKP Open Journal Systems Deutschland 2026–2028

diesen Beitrag auf Deutsch lesen

Building on TIB’s longstanding relationship with the Public Knowledge Project (PKP), a new consortium has been established to support PKP’s mission: collaborating with a global community to develop research-informed, free and open-source software, and to enhance the quality, diversity, and accessibility of scholarly publishing. TIB and PKP are asking academic organisations from Germany to become members of this consortium.

Sustaining OJS together by becoming a PKP member

Open Journal Systems (OJS) is the most widely used open infrastructure for scholarly publishing worldwide. Its development remains core to the Public Knowledge Project’s (PKP) activities. Being a free and open source software and research project, PKP enables open-access publishing without any license costs and is not dependent on commercial publishers.

Even free software needs reliable support. With the backing of a large and active community, PKP maintains and continuously develops the software. A stable financial basis enables PKP to continue this essential work.

PKP is financially supported by institutional members–universities and other organisations that contribute an annual membership fee. A new consortium, PKP Open Journal Systems Deutschland 2026–2028, has been established to enable easier memberships for Germany’s academic institutions.

A national consortium supporting an international open infrastructure

This new initiative is now open to all publicly funded German universities and research institutions. Through the consortium, organisations can become PKP members via a German infrastructure–in Euros, with clear processes and minimal administrative effort. TIB then forwards the membership fees to PKP. Together with contributions from members around the world, this support flows into PKP’s work and enables further development of OJS and the rest of PKP’s software suite (i.e., OMP and OPS).

This consortium is a strong example of the benefits that come from PKP’s distributed yet interconnected network of journals, institutions, and communities. TIB is ideally positioned to lead this effort, not only as a longtime user of the PKP software suite, but also thanks to its extensive experience managing and coordinating consortial agreements.

Why joining the consortium makes sense

• Ensuring long-term sustainability: Your contribution to PKP helps guarantee the ongoing development of OJS, OMP, and OPS, thus safeguarding an important open access infrastructure. More than half of all Diamond Open Access journals use OJS. By supporting PKP, you help sustain a system that provides free, high-quality scholarship to researchers.
• Investing in cost-efficient and fiscally responsible infrastructure: Your institution already benefits from OJS being freely available. If you host OJS—e.g., for university publishing activities—you do not have to pay any license fees. Your researchers publish in OJS-driven journals across the globe, almost all of which do not charge any fees partly because they themselves do not pay any licence fees.
• PKP membership: Your institution will become a PKP member in its own right and will have full membership benefits. Your membership will be acknowledged on the PKP website.
• Simple route to membership: By joining the consortium, you can easily become a PKP member through a German membership model. TIB will be prepared to help with your questions.
• Stable costs in euros: Membership fees are charged by TIB in euros, not Canadian dollars, and remain for the full duration of the agreement (2026–2028)
• Information and networking: You will receive information about PKP activities and can participate in member and community events. TIB will organise an annual consortium meeting to coordinate community needs and provide updates on PKP developments, typically with participation of PKP representatives. Consortium members will also receive regular digital updates on current PKP activities, including software development.

Sharing responsibility

PKP software and services are a central and crucial element of the German and international open access landscape. Open Journal Systems accounts for the huge majority of all Diamond Open Access journals. Without broad participation from institutions that benefit from OJS, its continued development is unnecessarily at risk. The German consortium offers a clear and practical way to take shared responsibility—with visible benefits for all participating organisations.

commitment to advancing open science and supporting the global research community,” said
David Nicholson, General Manager, Wiley Publisher Solutions. “By transferring KU to Annual
Reviews, we’re ensuring it has the specialized focus and nonprofit structure to best serve the
library and publisher communities it supports, while allowing Wiley to continue our broader
mission of empowering research and learning through innovation in scholarly publishing
worldwide.”“

Sehr schön formuliertes: „Verpisst Euch! Wir haben kein Interesse an Euch, weil man aus Euch keinen Profit herausschlagen kann.“

Funding Diamond Open Access

In case you weren’t aware, SciPost is a publishing infrastructure that provides Diamond Open Access to scientific papers. That means they are free to publish and free to read. They are funded by a consortium but are now struggling financially. They have recently circulated an open letter to the Community explaining their predicament and asking for help. I encourage you to read it and, if you can, to make a donation (or bully your institution to do so).

The open letter explains that SciPost is currently running at an average cost per paper of €500. That is much less than a typical APC for a mainstream journal but it is not a negligible cost. At the rate at which SciPost is publishing it amounts to about €1000 per day. SciPost currently attracts a significant level of sponsorship but it is not enough to support its current level of activity. Information on how to help SciPost can be found here. It is a worthy cause and deserves to be supported.

One area in which SciPost has not really taken of is Astronomy, where it has published very few papers. This may at be at least partly because of the Open Journal of Astrophysics (OJAp) which is also Diamond Open Access but runs in a very different and much cheaper way. A full breakdown of costs at OJAp is given here our annual running costs are about €5000 per year, which works out at less than €50 per paper (on average); that comprises a fixed component and a marginal cost of €10 per paper.

The main reasons for the large difference in running costs are: (i) SciPost maintains and runs its own platform; and (ii) it offers a copy-editing service. OJAp piggy-backs on arXiv (where most astrophysics research papers are found anyway) and expects authors to provide the final version of their own work. Neither organization pays referees or Editors. To enable it to run, SciPost employs about three staff full-time (2.9 FTE to be precise); OJAp has no employees and we keep our costs down by offering a ‘no-frills’ service. Instead of having a wide range of sponsors, we are entirely funded by Maynooth University. I am very grateful for that support, but we are run on a shoestring budget.

I have written before about what I think the future of Diamond Open Access could be like. I would like to see a range of Diamond Open Access journals offering a choice for authors and serving different sub-disciplines. Most universities nowadays have publishing operations so there could be network of federated journals, some based on arXiv and some based on other repositories and others with different models, such as SciPost. Perhaps institutions are worried about the expense but, as we have shown the actual cost, is far less than they are wasting on Article Processing Charges.

I don’t see other Diamond Open Access journals as competitors, but as allies with community-led ecosystem. I’d be more than happy to discuss how to start up such a journal on the OJAp model with anyone interested, and have already done so with some interested parties. As far as I’m concerned, the more the merrier! It is neither fair nor reasonable, however, that the expense of running a journal that serves the global astrophysics community should fall entirely on one small University in Ireland.

By all means support SciPost (and get your institutions to do likewise), but please also consider supporting OJAp. We are currently covering our costs but have no funds to make enhancements (such as a much-needed new LaTex template). If you can afford to make a donation to SciPost, then perhaps you can afford to make a donation to OJAp proportionate to our lower running costs? For example, if you give €10K to SciPost, could you give us €1K too? That amount would keep SciPost running for a day and OJAp for many months…

2/ Ich bin besonders froh darüber, dass der Artikel der erste Artikel in der komplett freien #ZeitschriftFürSprachwissenschaft ist. 2012 haben Martin Haspelmath und ich angefangen für #DiamondOpenAccess zu kämpfen. Damals gab die #DGfS fast ihren ganzen Etat für die #ZS aus, ca. 30.000€. Das ging an #DeGruyter, die gaben etwas für eine Assistentin aus, aber der Rest ging in Produktionskosten und Gewinn.

Ruben van de Vijver hat es dann geschafft, dass wenigstens die Aufsätze #OpenAccess wurden. Publikationskosten waren 1200€ pro Artikel. Ein Vögelchen hatte mir berichtet, dass de Gruyter intern mit 800€ gerechnet hat (Gewinn schon dabei). Die haben sich also sehr gefreut. Aber jetzt ist es vorbei und wir machen das alles selbst. Wozu braucht man denn auch einen Verlag?

Redet mit Euren Bibliotheken. Nehmt den Abzocker*innen die Zeitschriften weg und macht das selbst! Wenn Ihr die Rechte an den Zeitschriften nicht besitzt, schmeißt hin und gründet sie mit anderem Titel neu. Verlage können als Dienstleister mitwirken, dürfen aber nie die Titel besitzen.
