Title SuppressionsEditorial Expression of Concern
It has come to the attention of the editorial and management team for the Journal Citation Reports that there has been a problematic pattern of citations amongst the journals Nanoscience and Nanotechnology Letters, Journal of Biobased Materials and Bioenergy, Journal of Biomedical Nanotechnology, and Journal of Nanoscience and Nanotechnology (all published by American Scientific Publishers), and including a particular concentration of citations to the journal Bone Research (published by SpringerNature, in partnership with the West China School of Stomatology, Sichuan University, and the International Chinese Musculoskeletal Research Society).
The possibility of manipulation of citation metrics is a serious matter, and Clarivate Analytics remains the only bibliometrics provider to monitor, survey, and curate our data to identify anomalies that lead to distorted rankings.
We have initiated a process of investigation of the journals named above, along with affiliated publications. When we have completed a thorough review, we will take any appropriate action; this may result in one or more journals being removed from the JCR, with a possible further action of removal from indexing in Web of Science.
Because these citations have affected the published metrics for several journals, Clarivate Analytics is publishing this Editorial Expression of Concern to alert our users to this information.
Journals Suppressed from 2017 JCR Data (2018 release)
Metrics for the titles listed below are not published due to anomalous citation patterns found in the 2017 citation data. These patterns result in a significant distortion of the Journal Impact Factor and rank that does not accurately reflect the journal’s citation performance in the literature. The Journal Impact Factor provides an important and objective measure of a journal’s contribution to scholarly communication. In the interest of fairness and accuracy for all journals, the distortion of the Journal Impact Factor by an excessive concentration of citations gives rise to the need for suppression. JCR staff will monitor these journals going forward and the titles will be included in a future edition of JCR when the anomalous patterns are resolved. Coverage of these journals in Web of Science and other Clarivate Analytics products is not immediately affected by suppression from the JCR. However, the titles may be subject to review to determine if they continue to meet the quality and publication standards necessary for inclusion in Web of Science Core Collection flagship indexes (Science Citation Index Expanded and Social Science Citation Index). More information on journal suppression is available at:: http://wokinfo.com/media/pdf/jcr-suppression.pdf.

This table lists the categories for each journal (note that each journal may be included in multiple categories), the percentage of citations in the Journal Impact Factor numerator that are self cites, and the distortion in category rank due to self cites. The distortion in category rank is based on analysis of all journals in all categories of the JCR ranked both with and without the inclusion of self cites. Here distortion equals the percentage shift in rank with self cites included versus excluded.

Citation Stacking Suppressed Titles with Key Data Points*
This table lists the recipient and donor journal pairs along with the percentage of citations in the Journal Impact Factor numerator that are from the donor to the recipient (x% of the JIF Numerator cites to Recipient journal from Donor journal). The percentage exchange to the Journal Impact Factor years is the proportion of all citations from donor to recipient (all years) that reference the two years considered in the Journal Impact Factor calculation (x% of all citations from Donor to Recipient were concentrated in the Journal Impact Factor years).
