In this paper we present the first comprehensive bibliometric analysis of eleven open-access mega-journals (OAMJs).
OAMJs are a relatively recent phenomenon, and have been characterised as having four key characteristics: large size; broad disciplinary scope; a Gold-OA business model; and a peer-review policy that seeks to determine only the scientific soundness of the research rather than evaluate the novelty or significance of the work. Our investigation focuses on four key modes of analysis: journal outputs (the number of articles published and changes in output over time); OAMJ author characteristics (nationalities and institutional affiliations); subject areas (the disciplinary scope of OAMJs, and variations in sub-disciplinary output); and citation profiles (the citation distributions of each OAMJ, and the impact of citing journals).
We found that while the total output of the eleven mega-journals grew by 14.9% between 2014 and 2015, this growth is largely attributable to the increased output of Scientific Reports and Medicine.
We also found substantial variation in the geographical distribution of authors. Several journals have a relatively high proportion of Chinese authors, and we suggest this may be linked to these journals’ high Journal Impact Factors (JIFs).
The mega-journals were also found to vary in subject scope, with several journals publishing disproportionately high numbers of articles in certain sub-disciplines.
Our citation analsysis offers support for Björk & Catani’s suggestion that OAMJs’s citation distributions can be similar to those of traditional journals, while noting considerable variation in citation rates across the eleven titles.
We conclude that while the OAMJ term is useful as a means of grouping journals which share a set of key characteristics, there is no such thing as a “typical” mega-journal, and we suggest several areas for additional research that might help us better understand the current and future role of OAMJs in scholarly communication.
À partir de l’exemple d’un article scientifique publié dans la revue américaine en ligne PLoS ONE, on montre que la circulation d’une information scientifique sur le Net peut rapidement et massivement déborder des cadres habituels de la diffusion de la culture scientifique (médias, passeurs individuels et collectifs labellisés…). Cette recherche interroge ce que le « devenir trivial » d’une information scientifique dit des relations connaissances scientifiques/vulgarisation, science légitime/science amateur et plus généralement sciences/société.
Car si la circulation d’un « être culturel » hors de son champ de pertinence trouve un terreau fécond au sein même de la sphère scientifique, ses frontières avec les sphères profanes sont également autant des coupures que des coutures.
A megajournal is an open-access journal that publishes any manuscript that presents scientifically trustworthy empirical results, without asking about the potential scientific contribution prior to publication. Megajournals have rapidly increased their output and are currently publishing around 50,000 articles per year.
We report on a small pilot study in which we looked at the citation distributions for articles in megajournals compared with journals with traditional peer review, which also evaluate articles for contribution and novelty.We found that elite journals with very low acceptance rates have far fewer articles with no or few citations, but that the long tail of articles with two citations or less was actually bigger in a sample of selective traditional journals in comparison with megajournals.
This indicates the need for more systematic studies, because the results raise many questions as to how efficiently the current peer review system in reality fulfils its filtering function.
« A “mega-journal” is a new type of scientific journal that publishes freely accessible articles, which have been peer reviewed for scientific trustworthiness, but leaves it to the readers to decide which articles are of interest and importance to them. In the wake of the phenomenal success of PLOS ONE, several other publishers have recently started mega-journals. This article presents the evolution of mega-journals since 2010 in terms of article publication rates. The fastest growth seems to have ebbed out at around 35,000 annual articles for the 14 journals combined. Acceptance rates are in the range of 50–70%, and speed of publication is around 3–5 months. Common features in mega-journals are alternative impact metrics, easy reusability of figures and data, post-publication discussions and portable reviews from other journals. »
« Aim. To determine the characteristics of megajournal authors, the nature of the manuscripts they are submitting to these journals, factors influencing their decision to publish in a megajournal, sources of funding for article processing charges (APCs) or other fees and their likelihood of submitting to a megajournal in the future.
Methods. Web-based survey of 2,128 authors who recently published in BMJ Open, PeerJ, PLOS ONE or SAGE Open.
Results. The response rate ranged from 26% for BMJ Open to 47% for SAGE Open. The authors were international, largely academics who had recently published in both subscription and Open Access (OA) journals. Across journals about 25% of the articles were preliminary findings and just under half were resubmissions of manuscripts rejected by other journals. Editors from other BMJ journals and perhaps to a lesser extent SAGE and PLOS journals appear to be encouraging authors to submit manuscripts that were rejected by the editor’s journals to a megajournal published by the same publisher. Quality of the journal and speed of the review process were important factors across all four journals. Impact factor was important for PLOS ONE authors but less so for BMJ Open authors, which also has an impact factor. The review criteria and the fact the journal was OA were other significant factors particularly important for PeerJ authors. The reputation of the publisher was an important factor for SAGE Open and BMJ Open. About half of PLOS ONE and around a third of BMJ Open and PeerJ authors used grant funding for publishing charges while only about 10% of SAGE Open used grant funding for publication charges. Around 60% of SAGE Open and 32% of PeerJ authors self-funded their publication fees however the fees are modest for these journals. The majority of authors from all 4 journals were pleased with their experience and indicated they were likely to submit to the same or similar journal in the future.
Conclusions. Megajournals are drawing an international group of authors who tend to be experienced academics. They are choosing to publish in megajournals for a variety of reasons but most seem to value the quality of the journal and the speed of the review/publication process. Having a broad scope was not a key factor for most authors though being OA was important for PeerJ and SAGE Open authors. Most authors appeared pleased with the experience and indicated they are likely to submit future manuscripts to the same or similar megajournal which seems to suggest these journals will continue to grow in popularity. »
« PLOS ONE (formerly PLoS ONE) is an international open access online journal published by the Public Library of Science. The periodical covers all science and medicine categories and has published as many as 28,852 documents from 2007 to 2011. PLOS ONE will be used to show the range of journal metrics and informetric methods regarding validity, practicability and informative value. To assess this data as specifically as possible and to address all relevant factors, the evaluation is split into five dimensions, each of which involves distinct metrics. The five dimensions are journal output, journal content, journal perception, journal citations and journal management. Each of them is pointed out in the process of the analyses, and all significant evaluation results are presented. The results show that PLOS ONE has experienced an enormous development. Because of a relatively low rejection rate of 31%, its openness towards a multitude of different research areas, an internationally large peer review community, and its open access, a plurality of documents can be published in comparison with a print-journal or other online periodicals. The results of the evaluation indicate that PLOS ONE should be assessed from numerous perspectives because there are a variety of indicators beyond the impact factor that can be made use of in order to evaluate exhaustively the standing of the journal as well as its prestige and impact. »
