One year ago, TVCG started to publish all papers that were accepted after a rigorous journal-style review to the IEEE Visualization Conference and to the IEEE Information Visualization Symposium. This increased the number of published papers from 65 in 2005 to 164 in 2006. Besides the 87 papers in the conference issue, the number of papers in the five regular issues grew to 77. We conducted a subscriber survey right after the publication of the 2006 conference issue that showed overwhelming support for this change. Subscribers consider the additional conference papers to be a significant increase in value to the journal and they welcome the improved paper quality at the conference due to the journal-style review process. A concern that the conference issue could take away publication space from regular submissions was raised. However, based on an enlarged page budget, we were able to increase the number of papers in the five regular issues of 2007 to 89. The conference issue that will be the November/December 2007 issue will contain the VIS and Infovis papers similarly to last year. Thus, I am glad to report that TVCG continues to grow in its 13th year and I am looking forward to your constructive comments for further improvements.
Starting with 2007, the IEEE Computer Society transactions adopted an online first publication model, meaning that an accepted manuscript will be posted online shortly after all of the publication materials have been received. The PDF is stamped as a preprint and is made accessible through IEEE Xplore and through the IEEE Computer Society Digital Library. After the paper has been edited, it will then be restamped as a Rapid Post, indicating that the paper is complete with the exception of pagination. As we constantly try to improve the average time from submission to print, the new model significantly reduces the time from submission to publication, with many benefits for the authors and readers of the journal. I encourage you to browse through the preprints and rapid posts in the CSDL and through the forthcoming articles in Xplore.
The authors and reviewers of TVCG may have noticed that the Manuscript Central system for online submission and peer review went through a major version upgrade in March 2007. I apologize for any delays you may have experienced during this phase and I am very grateful to the entire staff at the IEEE Computer Society for making this transition as smooth as possible.
Finally, I am happy to introduce Helwig Hauser, Alan M. MacEachren, Jos Stam, and Ross Whitaker, who have recently joined TVCG as Associate Editors. Below are biographical sketches listing their accomplishments and areas of expertise. The Editorial Board is pleased to welcome these outstanding individuals to their new role.
