Editor's Note

Thomas Ertl
2009 IEEE Transactions on Visualization and Computer Graphics  
Computer Graphics (TVCG), I am attending the IEEE VisWeek '08 in Columbus, Ohio, and I am delighted to see hundreds of people eagerly browsing through the November/December 2008 issue of TVCG and absorbing this unique collection of 78 papers reporting on the latest and best research results in visualization. As the year 2008 is almost over, I am happy to report that the journal continues to be in a very good state as we move into the 15th year of its existence. The year 2007 was the second year
more » ... in which the papers accepted for the IEEE Visualization Conference and the IEEE Information Visualization Conference were published together in one issue of TVCG after undergoing a tworound journal-style review process, and I can now report on the fi nal statistics for this year. A total of 520 manuscripts were submitted to TVCG in 2007, out of which 131 were published or are in the publication queue. This results in an acceptance rate of 29.5 percent, which is consistent across regular submissions and conference submissions. TVCG continues to offer authors remarkably fast processing of submitted manuscripts: The average time from submission to fi rst decision is less than three months and the average time from submission to acceptance is less than fi ve months. Our Online First Publishing Model guarantees that, on average, an accepted manuscript will be published and available online about six months after submission. The preliminary numbers for 2008 indicate that we are still cutting down on the duration of the review process while maintaining the high number of submissions. A slight decline in the number of submissions to the conference issue should be compensated for by an increase in regular submissions. Unfortunately, the impact factor of TVCG as computed by Thomson Scientifi c went down to 1.6 in 2007 from 1.79 in 2006. While a similar trend can be noted for most other journals in the fi eld of computer graphics and visualization, we expected this for TVCG. Although we continue to see an increase in citations of TVCG articles, 2007 was the fi rst year for which the impact factor was normalized by a signifi cantly larger number of papers published in the conference issue of 2006. It will take another year until the effects of this change will level out. Nevertheless, TVCG clearly is and remains the number one journal with a signifi cant coverage of visualization and the journal ranked second for computer graphics in general. Looking forward into 2009, I hope that the readers of TVCG will appreciate the following improvement: Starting with this issue, the table of contents will be sorted by categories to give you a better overview of the published articles and to let you focus on the papers you are most interested in. This will also allow us to improve the visibility of the special sections where we publish extended versions of the best papers of various conferences and symposia in our fi eld. I will continue to invite the authors of best papers of those events that help extend the scope of TVCG while maintaining its high quality. Please be assured that the review process for these invited papers is very rigorous with respect to our rule requiring at least 30 percent new material. As a result, the accepted papers are clear improvements of already very good conference publications and should be cited accordingly.
