Variations in pricing of the article processing charges

Version en français (French version)

From the datasets downloaded from the Directory of Open Access Journal, we did some analysis. We found that among the journals that do offer article processing charges (APC), 87 % of them offer variations. So that the APC that the author expects to pay could be higher or lower. Those fluctuations depend on many factors. For example an article that requires language editing would have higher APC and if the author comes from a low/medium income countries then the APC will decrease. The table one shows the percentage of journals offering variations in pricing. The table 2 shows the list of the most frequent factors that contribute to APC variations.

Table 1. Percentage of journals offering variations in pricing (2015).


Table 2. Frequency of sub-types of variations.


Please note that we did not count every variation found. For example, variations likely based on simultaneous print versions of journals such as colour charges were not capture.

Variation dans les frais de publications de l’article

Version en anglais (English version)

Nous avons analysé la liste de journaux en libre accès téléchargé du site internet du répertoire des revues en libre accès (DOAJ). Nos résultats nous démontrent que parmi les journaux qui adoptent comme modèle d’affaire la méthode de frais de publication de l’article, 87 % de ces journaux offrent une variation des frais de publication. Cela signifie que les frais que l’auteur s’attende à payer peuvent augmenter ou diminuer. Les frais supplémentaires peuvent être dû pour plusieurs raisons. Par exemple, il peut y avoit une charge additionnelle si le nombre de page excéde la limite fixée par l’éditeur. De la même manière plusieurs raisons peuvent expliquer une réduction des frais de publication de l’auteur. Par exemple, l’auteur a utilisé le gabarit de l’éditeur pour rédiger son article. Le tableau 1 montre le pourcentage de journaux dont les frais de publication de l’article peuvent varier. L’année dernière des résultats semblables ont été publiés dans cet article.

Nous n’avons pas compté tous les types de variations. Par exemple, les frais de publication qui semble d’être plus pertinente aux versions imprimé (frais de couleurs) sont omis ici.

Top 10 publishers in DOAJ (by number of titles) 2014 to 2015

by Heather Morrison & Guinsly Mondésir

There have been a few changes in the collection of fully open access journals listed in the Directory of Open Access Journals in the past year, as demonstrated by the following chart. While Hindawi and BioMedCentral remain the largest publishers (by number of journals, not number of articles), traditional publisher De Gruyter has gone from no titles in DOAJ in 2014 to 3rd largest DOAJ publisher and Elsevier is now the 7th largest DOAJ publisher by number of journals. Figures are based on an analysis of publisher by size drawn by DOAJ metadata downloaded in May 2014 and May 2015. Full data is available in the OA APC dataverse

Note that publisher size by title offerings is different from publisher size by number of articles published, which is outside the scope of our study. The percentage of journals in DOAJ published by the top 10 publishers has increased slightly, from 14% to 16%. This is likely not a significant difference, but perhaps an indication of a trend to watch. Note that we have made no attempt to correct for variations in publisher name listings; we recommend instead that publishers update their information in DOAJ and ensure correct entry for future research and researchers.
