Although, in some cases, the publication Apoptosis inhibitor fees vary according to the type of article (i.e. original articles, reviews or letters), it is worth noting that, regardless of the quartile ranking, the most frequently charged fee is $ 3000 (€ 2318). Table S 3 reports the copyright and see more self-archiving policies declared by publishers of the journals surveyed in Table S 2. As copyright rules established
by the same publisher may include various models, Table S 3 also provides the links to the publisher copyright policy so that authors can access details of specific policies. As expressly stated in their copyright policies, Table S 3 shows that half (12 out of 24) of publishers adopt a CTA; 4 out of 24 use a mixed system envisaging an ELF
or a CTA, according to specific journals in their portfolios or to types of articles, and 4 out of 24 propose either a CTA or a CCA. In only one case (Nature Publishing Group) does the copyright policy provide an ELF or a CTA or a CCA according to the type of article (i.e. the CCA is used Ro 61-8048 for articles reporting for the first time the primary sequence of an organism’s genome). With reference to the range of colours reported by SHERPA/RoMEO database, Table S 3 shows that 6 out of 24 publishers are classified as “green”, 2 as “blue”, 8 as “yellow” and 5 as “white”. For three publishers no information was retrieved from SHERPA/RoMEO. Discussion The remarkable number of Q1-ranked journals indicates the high level of publications produced by researchers and clinical staff of the three institutions involved in the study. This means that authors carefully consider IF values when deciding where to target their work, notwithstanding the widely-recognised biases of the raw IF value . Research Bay 11-7085 quality assessment is still a much-debated issue, also in the light of innovative parameters
(i.e. webometrics ). This is not, however, the place to discuss this relevant topic and its impact on public health. Where journal business models are concerned, it is worth mentioning that according to administrators of public funds and opinion leaders in the OA debate, the hybrid formula, which is based on a double income (subscription fees and article publication charges), is criticised for increasing publishers’ revenues while neither incurring any risk, nor reducing subscription costs. Publishers claim they will not “adjust” subscription costs until income from the paid OA option becomes steady. On the subject of publishing costs, Michael Jubb claims that “policymakers […] should also promote and facilitate a transition to gold open access, while seeking to ensure that the average level of charges for publication does not exceed circa £ 2,000” .
