eCM Supplements of conference abstracts
The eCM Journal (Eur Cell Mater) council decided in June 2017 to discontinue and remove all old supplements published in eCM journal. This decision was based upon the unfortunate situation that randomly since 2013 eCM conference abstract supplements were being used in the JCR / Clarivate Analytics calculation of eCM journal's impact factor.
All eCM supplements were pure conference abstracts, which should not be included in an Impact Factor calculation ("non-citable item"). eCM and many other journals do not even allow manuscripts to use citations to conference abstracts. This is reflected from the fact that from the 17 supplements (from 2014 and 2015, used for the calculation of the 2016 JCR Impact factor) there were zero citations. eCM Supplements did not have a DOI, are/were not searchable on PubMed, are/were not deposited in CLOCKSS and are/were not allowed to be cited by eCM, as they are not peer reviewed. Despite this, JCR / Clarivate Analytics unfortunately have used these non-citable item supplements from eCM in the Impact Factor calculation for 2016. This has wrongly caused a drop of eCM's 2016 Impact Factor from 4.633 to 4.000 due to this situation. We are still in discussions with JCR / Clarivate Analytics to solve this miscalculation. Unfortunately this would account for approximately 15% of our citable items, even though these are displayed as non-ciatble on the JCR files.
The eCM Journal council have therefore decided to both stop all production of eCM supplements with eCM journal and also has stopped hosting all past supplements. The eCM Journal council agreed to remake all old supplements, without any reference to eCM journal, without eCM's ISSN number, without reference sections and each combined into 1 PDF for oral and 1 for poster. These Meeting Abstracts are being hosted on a separate new web site ecmconferences, which is not part of the eCM (Eur Cell Mater) journal.
For all future hosting of meeting abstracts a new abstract template has been designed.
Therefore, costs associated with hosting of these eCM abstracts have also dropped dramatically due to the less labour intensive production of these single PDF collections.
If journals allow abstracts to be cited, they may be cited but not as ecmjournal abstracts, only through the hosting site of ecmconferences, which is not part of eCM journal.
