The Directory of Open Access Journals (DOAJ) is a collaboratively curated online directory for Open Access journals founded at Lund University. The directory is run by an independent non-profit organization. Journals must meet various requirements to be included in the directory, such as 
appropriate quality control procedures and immediate Open Access without an embargo period.

The library of TU Graz has been supporting the Directory of Open Access Journals (DOAJ) since 2016.

KOALA (Konsortiale Open-Access-Lösungen Aufbauen) is a German acronym translating to "Establishing Consortial Open Access Solutions".

The KOALA project aims to establish alternative and fair solutions to the APC (Article Processing Charge) model for Open Access publishing.
Funding is provided collectively by the academic community, research institutions, libraries, and associations.

This initiative enables selected journals to be published as Diamond Open Access. This means that there are no costs for either authors or readers.

Following the successful first phase of the project (2021–2023), six book series and journals from the fields of media and social sciences have been funded since 2023 by nearly 70 institutions within the KOALA consortium.

During the second phase of KOALA (2024–2026), the TU Graz Library is contributing to the funding of the KOALA "Mathematics/Informatics 2024" journal bundle.

As part of this bundle, the peer-reviewed journal J.UCS – Journal of Universal Computer Science, published by TU Graz, will continue as a Diamond Open Access journal in 2025.

SciPost - TU Graz supports alternative Open Access publishing portal

As the first consortium worldwide, ten Austrian research institutions, including TU Graz and the FWF, support the publication portal SciPost. This Open Access platform for physics publications is financed through an international cost-sharing model.

SciPost is free of charge for both readers and authors. Articles can be submitted via the preprint server arxiv.org. The reviews and replies from the Open Peer Review process are freely accessible on the SciPost platform.

Publications in SciPost Physics, SciPost Physics Proceedings and SciPost Physics Lecture Notes replace publication in traditional journals in all areas of physics.

On request, articles published on SciPost are also included in the TU Graz repository.

SCOAP³ - Sponsoring Consortium for Open Access Publishing in Particle Physics

The University Library supports the global Open Access project SCOAP³ on behalf of TU Graz, within which the entire scientific output in the field of high energy physics (HEP) is to be made available on Open Access without additional costs to scientists. Therefore, since 2014, HEP content from publishers Elsevier, Hindawi, Institute of Physics, Jagiellonian University, Oxford University Press, and Springer has been available worldwide on Open Access. From January 2018, the HEP content of the journals Physical Review C, Physical Review D, and Physical Review Letters of the American Physical Society will also be part of SCOAP3 and therefore be converted to Open Access.

During the pilot phase (May 2021-November 2022), 133 books were successfully transitioned to Open Access. This led to a 13% increase in book download figures. Since 2023, there has been an ongoing book program: SCOAP3 Books.
