Welcome to seminars in thrombosis & hemostasis 2015: new (2013) impact factor and most highly cited articles.

Welcome to the start of another year with Seminars in Thrombosis & Hemostasis (STH). This is my 7th year as editor-in-chief, and my 10th year of editorial association with this journal, having originally served as a regional editor. First, I sincerely wish to thank all the contributors to STH over the past years, as well as the guest editors for these issues, and of course, the current and past senior and associate editors of the journal. There will be some changes to the editorial team over the forth coming 12 months, with an expansion of this team currently in plan. Also, Dr. Catherine Hayward has indicated she would like to step down from her role as senior editor. We sincerely thank her for her support in previous years and wish her continued success in her work. Last year represented a milestone for this journal, representing the 40th year of publication, a landmark that we celebrated with two special 40th anniversary celebratory issues.1,2 I will also take this opportunity to thank the journal production team at Thieme Medical Publishers for their high production standards and for facilitating both the print and online issues of the journal. In particular, I would like to thank Subhankar De, the production editor for STH for managing the production process of STH issues and articles. I also wish to thank Kelly Coffey, a journals coordinator for Thieme Medical Publishers, as well as other key people at Thieme, some of who prefer to remain unnamed, for the additional support provided over the recent years. This is also a fitting time to once again reflect on our journal’s impact factor, which was 3.693 for 2013. This represents a drop from our 2012 impact factor of 4.216 (►Fig. 1). I am hopeful that this pattern reflects some stabilization of the STH impact factor at around 4 over the coming years. It might be of some interest to note that the impact factor for most thrombosis and hemostasis focused journals fell in 2013 comparedwith 2012 values (►Fig. 2). The reason for this generalized fall in impact factor for thrombosis and hemostasis focused journals is unknown, although it could be at least in part due to continued development of additional publishing avenues from open access models. I have also previously highlighted,3,4 and would continue to assert, that the impact factor is not the onlymarker of journal “quality” that we should consider, given the existence of other biometric markers and the limitations of any individual marker (including the impact factor) as a “quality” indicator. Nevertheless, for the potential interest of the readership and contributing authors, I have listed the highest 2013-cited, 2010/2011-published, contributions from this journal in►Table 1.5–62 These contributions identify those publications most contributing to the 2013 impact factor, and each was cited five or more times in 2013.
