APCs — Mirroring the impact factor or legacy of the subscription-based model? Descriptive statistics.


This blog post is part of a series that explains the study “APCs — Mirroring the impact factor or legacy of the subscription-based model?” of OA2020-DE. After discussing the summary statistics of each variable separately, we present several plots and simple statistical measures showing relationships between two variables. However, keep in mind that finding correlation between two variables does not necessarily imply causality. To state a causal relationship, one needs to run a careful regression analysis, which will be presented in the next blog post.

APCs — Mirroring the impact factor or legacy of the subscription-based model? An introduction.


OA2020-DE prepared a report that is a first step forward to answer the question whether the large-scale open-access transformation of scientific journals is a financially viable way for German research and higher-education institutions. Usually, article processing charges (APCs) are charged to the submitting/corresponding author’s account for publishing scientific articles in open access. In Germany, the DFG-funded publication funds accept the costs for APCs up to EUR 2.000. With the ongoing open-access transformation, APCs are gaining importance as relevant business model for open-access journals. For a financial assessment, it is of utmost importance to predict the APC-levels after a comprehensive journal flipping — both the average APC and the distribution of APCs. To predict APCs, we need to know the factors determining APC-levels today. This is the core of the paper.

With data from OpenAPC, which is part of the INTACT project at the Bielefeld University Library, Germany, we analyzed the determinants for APCs actually paid (in contrast to catalogue prices). Price-determining factors could be the reputation and quality perception of a journal proxied by its citation impact, whether the journal is open access or hybrid, the publisher and the subject area of the journal. We are going to present and discuss the core results of the study in several blog posts. For the statistical and technical details, we refer to the full report.

Second OA2020-DE transformation workshop at University Bielefeld


Workshop on open-access transformation focuses on framework conditions

On 17 and 18 October 2018, an open-access transformation workshop organised by OA2020-DE took place for the second time. The aims of this workshop were to network the signatories of the "Expression of Interest" of the OA2020 initiative, to win new supporters and to exchange information on concrete activities to implement the open-access transformation. This time, the participants mainly consisted of open-access officers and library directors. The first day focused on strategies for open-access transformation at national and international level, while the second day focused on concrete transformation processes at research institutions and university libraries (Agenda).

Recommendations on quality standards for the open access provision of books [Update]


Quality standards in science and research are important, as the reporting on fake science (better: junk science) has made clear once again (see here). This not only applies to journals and conferences, but also to books. Therefore we developed "Recommendations on quality standards for the open access provision of books" together with Knowledge Unlatched and the publisher transcript. The aim is to provide authors, publishers and libraries with a practical guideline describing criteria for the production, distribution and financial participation in the open access provision of books. It is important to know which services can be offered or expected, both for publishers who provide open access services for books and for libraries who want to enable an open access position for books through financial participation.

In order to facilitate the entry into this process, especially for smaller publishers, we propose implementing the recommendations in two phases. Above all, quality standards in the areas of formats, metadata, accessibility, licenses, costs and distribution are relevant in the entry phase to the open access position of books. Phase two expands these standards and adds quality inspection criteria (peer review), as well as text and data mining.

The updated recommendations are available in German and English:

Many thanks to the representation of German-speaking university publishers, which has actively contributed to the further development of the standards and also deals with the topic itself.
