PLOS APCs 2018: 3 – 7% price increases

From December 2017 to December 2018, APC prices for all PLOS journals were increased by $100 USD, resulting in percentage increases from 3% – 7%. All price increase percentages are higher than the U.S. Department of Labour Statistic’s 2.2% Consumer Price Index increase from November 2017 – December 2018. The majority of percentage price increases (4/8) are higher than the average increase in a U.S. faculty member’s salary according to the American Association of University Professors of 3% (from April 2018). The most surprising increase from my perspective is the 7% increase to the APC of PLOS ONE (twice the increase of faculty salaries, thrice the US CIP increase), because as PLOS’ pioneering megajournal, PLOS ONE’s practice is peer review limited to assessing whether the science is sound. Peer review is done by volunteers and coordinated by PLOS using a highly automated approach; it is difficult to understand how PLOS’ contribution to PLOS ONE articles justifies an APC of approximately $1,600 USD.

Medknow in 2018: growing fast!

by Hamid Pashaei and Heather Morrison

Medknow is a commercial scholarly journal publisher based in India, which was acquired by Wolters Kluwer in 2011. The analysis of Medknow’s journals in 2018 shows that there has been a significant increase in number of their journals, with 23% increase comparing to 2017. It appears that most of Medknow’s journals are published in collaboration with different universities and societies in the filed of medical research.

Due to variety of affiliated communities who collaborate with Medknow, finding information and collecting data from Medknow’s website is complex. Some data about the processing charge of journals were not available, and the currency was provided in different units (INR, USD, CNY, …) that could also be confusing for potential authors. From the journals for which data was available, 71% charged no processing fee. While the cost for the majority of paid journals were fixed comparing to 2017 data, there were also an increase in cost for some journals. The processing charge for publishing journals is based on APC (Article Processing Charge), with only a few exceptions that were based on APPC (Article Page Processing Charges).

Elsevier in 2018: decrease in number of fully OA journals

Highlights: in 2017, we found that Elsevier was publishing a large number of fully open access journals with no article processing charges due to society or university sponsorships. In 2018, 88 of these titles have been transferred back to the society or university. There has been a drop in the number of fully OA journals published by Elsevier, from 416 to 328 journals. The majority of Elsevier’s fully OA journals are still non-charging. The average APC for Elsevier fully OA journals in 2018 is $1,470 USD, up 6% from 2017.

This is a subset of the 2018 version of the main spreadsheet for the open access article processing charges project. The columns for the 2018 – 2017 comparison on the main Data tab are D, 2018 APC publisher website original currency, and N for 2017. Pricing is from the Elsevier APC price list; “no publication charge” is our standardized term, on the Elsevier PDF this is “Fee waived for author”. If you are interested in the journals that have transferred back to a society or university, go to the next spreadsheet:


In 2017 we noted that there are many Elsevier journals that are “fee waived for author” due to sponsorships and decided to begin tracking these sponsorships and an interesting model of partnership, e.g. statements on the Elsevier webpage that made it clear that Elsevier was publishing on behalf of a society or university that retained copyright. Column I, the notes field for 2018, is where you will find details on journals transferred back to the publisher. This information is gathered from the Elsevier website – journal title list, not the APC price list.



 In April 2017, Elsevier was publishing 416 fully open access journals. As of April 2018, this number had decreased to 328 journals, a decrease of 88 journals or 20% of the total. Data is from the Elsevier APC price list (conversion necessary for data manipulation).E2018nonchargingjpg

Most fully OA journals published by Elsevier do not charge publication fees (61% of the total) due to sponsorship by societies or universities. This percentage is about the same as the previous year (57% non-charging). A survey conducted in 2017 found that almost all non-charging journals were published by Elsevier on behalf of a society or university, with copyright ownership retained by the society or university.

A survey of the Elsevier website for OA journals identified as non-charging in 2017 was conducted over the summer. These journals are still listed on the Elsevier website if not the APC price list and information is provided about the current status of the journals. This is a good practice. A total of 88 journals were found to have been transferred back to the society in 2017 or 2018, or scheduled to be returned to the society or university publisher.

For example, a notes about the The Revista Mexicana de Bioversidad indicated that the journal:

Transferred back to the society as of 2018

The average APC for Elsevier’s charging, fully OA journals in 2018 was $1,470 USD, up from $1,384 USD in 2017, an increase of 6%.
