Open Access Journals
Intro Facts about Open Access Journals open-access.network (2026) ( CC BY 4.0 International ) The key takeaways from this article are 1 Open access journals are journals whose articles are available and reusable worldwide free of charge and without restrictions immediately on publication. 2 Most open access journals do not charge their authors for publishing articles. In other cases, the author-pays model is common. 3 The content published in open access journals is searchable in the usual databases and search engines – the Bielefeld Academic Search Engine (BASE) specialises in open access content. Definition Open access journals are journals whose articles are available and reusable worldwide free of charge and without restrictions immediately on publication. As a rule, contributions in journals that meet this definition are published under a Creative Commons licence granted by the authors. The publishers of these journals are granted only a non-exclusive right of use by the authors. Open access journals are the primary medium for what is known as gold open access to scholarly articles. If a journal does not levy article processing charges (APCs) , this is often referred to as diamond open access . Through gold or diamond open access, articles achieve the widest possible dissemination and are available to and reusable by researchers and all other interested parties as fast as possible. In this way, the visibility of research results is enhanced and their citation frequency is often increased ( Piwowar et al., 2018 ). open-access.network ( CC BY 4.0 International ) Open Access and Closed Access Practical Tip An overview of the requirements that open access journals must satisfy, and concrete criteria that authors can use as a guide when choosing a suitable publication venue can be found in a German-language presentation entitled “ Qualität von OA-Zeitschriften – Wo publizieren und wo lieber nicht ” [Quality of open access journals – Where to publish and where better not to]. Practical Tip The following tools can be helpful in finding suitable OA publication venues for your own manuscript: oa.finder (a tool for searching for scholarly publication venues; developed as a project by open-access.network ) B!SON (Open Access journal recommender, developed by TIB and SLUB Dresden ) EZB (Search tool for open access journals and funding options). The Electronic Journals Library (EZB) has expanded its services and can now be used as a central tool for searching for journal-level information on the coverage of article processing charges (APCs) by authors’ own institutions. The search tool can be used, for example, to identify contact persons, specific requirements or financial limits, and specific procedures for submitting invoices to the respective institutions. You can find further information on the new functions of the tool he re . Quality Assurance and Impact Measurement Find an introduction here. In terms of quality, there is no difference between open access and closed access (i.e., subscription-based ) journals. As is the norm in the case of scholarly journals, manuscripts undergo a quality assurance procedure – mostly peer review – before publication. In the context of open science and the idea of a transparent scientific process, some open access journals even go one step further and offer open peer review . By disclosing the identities of all participants open, and possibly also the reviews ( Ross-Hellauer, 2017 ), quality assurance becomes a community process, thereby ensuring constructive criticism. Moreover, the free availability of the full texts has the advantage of making it easier to detect plagiarism and errors. Where customary in the discipline in question, some open access journals occasionally also practise a form of editorial review.

Funding open access articles – What are the options? open-access.network. https://doi.org/10.5446/73596 Funding The main difference between open access and closed access journals lies in the free availability and reusability of the former and in the way they are funded . In the case of traditional closed access (subscription-based) journals, the readers, or their institutions and scholarly libraries, pay high fees for access to the articles. Open access publications, by contrast, can be used free of charge. Hence, funding must take place via a different channel. The author-pays model, whereby authors pay article processing charges (APCs) to publish their contributions, is very widespread. A substantial proportion of open access journals use a diamond open access model, which means that no fees are charged to readers or authors. Diamond open access journals are typically funded by professional societies, scientific institutions, or library consortia. By now, many closed access journals offer authors the option of paying a high fee to make individual contributions freely available. The publishers of these so-called hybrid journals therefore generate additional revenues without there being a corresponding decrease in subscription prices. Because of this so-called double dipping on the part of publishers, hybrid open access is quite controversial. Via transformative agreements with commercial publishers – for example, those negotiated by the German initiative Projekt DEAL Consortium (formerly Projekt DEAL) – the costs of these hybrid APCs are increasingly being covered up to a contractually specified amount by library consortia with the aim of transforming the hybrid journals into open access journals in the long run. However, critics question the effectiveness of these agreements. Several analyses have found that the transition from subscription-based to purely open access journals often fails to materialize and is not adequately encouraged ( Mittermaier, 2025 ). In addition, the agreements could consolidate market and dependency structures to the advantage of major publishers, and their cost calculation sometimes lacks transparency or is questionable ( Ziegler & Dirnagl, 2024 ). Furthermore, it is feared that transformative agreements channel the flow of publications to a few major publishers, thereby threatening bibliodiversity ( Kaden, 2023 ). Many research funders and institutional publication funds refuse to fund OA publication fees for contributions to hybrid journals (see e.g. Plan S ). To circumvent these exclusion criteria, some major publishers have established "mirror journals" , that is, OA versions of subscription journals whose thematic focus, editorial boards and peer review processes are largely identical to those of the corresponding subscription journal. Both the cOAlition S and the German Research Foundation (DFG) consider such journals to be de facto hybrid journals whose articles are not eligible for funding ( Voigt, 2022 ). open-access.network ( CC BY 4.0 International ) Source: altmetric.com Self-Archiving Green open access can also be provided to publications in closed access journals by making them available free of charge in repositories . Under German copyright law (UrhG), scientific contributions published in conventional journals may, under certain conditions, be self-archived in a repository. This is referred to as the “ secondary publication right ”. Impact The Journal Impact Factors , a metric for the citation frequency of articles published in a given journal, are published in the Journal Citation Reports , which also covers open access journals. However, the misuse of the Journal Impact Factor to evaluate outputs of scholarly research has been strongly criticised (see the Declaration on Research Assessment, DORA ). Altmetrics have emerged as an alternative to the traditional bibliometric indicators. They capture the diverse reactions to scholarly publications on the Web. Finding Content The content published in open access journals is indexed in many locations and is searchable in the usual databases and search engines. The Bielefeld Academic Search Engine (BASE) specialises in open access content. In journal and article databases, filter options offer the possibility of limiting the search to open access content. This is the case, for example, in the Electronic Journals Library (the option "free for everyone") or in the Web of Science. GoTriple is an interesting discovery platform for open access content from the social sciences and humanities. A useful open source tool for finding open access versions of scholarly publications is Unpaywall , which is available as a browser extension for Firefox and Chrome ( Piwowar et al., 2018 ). Finding Open Access Publications Numerous search engines specialise in open access. This presentation provides an overview of how to find free scientific literature. Open Access in Specific Disciplines The introductions to open access in specific disciplines on open-access.net are also a good starting point. Directory of Open Access Journals (DOAJ) The central database for open access journals is the DOAJ, which can also be searched by field. Publishing Open Access Journals Find an introduction here. German-Language Presentation on “Founding Open Access Journals” The slides of this presentation entitled “ Open-Access-Zeitschriften gründen – woran muss ich denken? [Founding open access journals – What should I bear in mind] provide valuable tips about the things that editors should consider before launching an open access journal. Founding A Journal Do you see a need for a new journal in your field, and would you like to publish it as an open access journal? Many open access journals are set up by scholars and scientists. Because there are now a large number of options from a discipline-specific, technical, and financial perspective, we would recommend, as a first step, that you talk to the open access experts at your institution. Many institutions offer their researchers the possibility of supporting the creation and management of independent open access journals, for example, via the software application Open Journal Systems (OJS) . One example is the TIB – Leibniz Information Centre for Science and Technology and University Library, which operates a publication platform, TIB Open Publishing , on which open access journals can be hosted with OJS. Although open to all fields, the focus is on the technical sciences and the natural sciences. In addition, there are also a number of open access publishers – and also conventional publishers, which are increasingly switching to open access publications – under whose umbrella you could set up your journal. We recommend that you take a look at our discipline-specific pages to see which publishers in your field already have open access offerings. The Open Access Journals Toolkit can also provide helpful guidance on founding and operating an open access journal. If you want to convert an existing subscription-based journal to open access rather than founding a new journal, you can find further information on how to do so on our Converting Journals to Open Access page.
