With the first issue of volume number C57, the IEEE Transactions on Computers ( TC) will enter a new year of publication, a long journey started more than 50 years ago. If you are an old timer like me who enjoys navigating through dusty paper copies of TC in your institutional library, you will be surprised to find that, initially, volumes were numbered EC1 through EC16. This reflects the origin of this publication as derived from the IEEE Professional Group on "Electronic Computers." It was then changed to its current name (simply "Computers," by omitting the redundant or just obvious "Electronic") with the 17th volume as C17. Significantly, this long tradition has established TEC/TC as the oldest among all transactions sponsored by the IEEE Computer Society (the next oldest is the Transactions on Software Engineering, which started in 1975, followed by the Transactions on Pattern Analysis and Machine Intelligence in 1979). Throughout the years, the organization of TC has experienced significant changes; a significant change occurred 10 years ago when the operational organization was moved from a strictly volunteer-based team (mostly associated with the Editor-In-Chief) to include a full-time professional entreprise as run daily by the staff of the IEEE Computer Society office in Los Alamitos, California. This change was accelerated by the Web-based facilities provided for TC as well as all CS-sponsored publications. The volunteer base has also undergone changes: The Editorial Board has been enlarged and, in line with most Transactions, TC is now led by an Editor-In-Chief (EIC) and an Associate EIC (AEIC); all EICs and AEICs of IEEE TC are listed below in Table 1 with the volume numbers corresponding to their appointment.

I note that, to the satisfaction of electronic media lovers and in line with modern times, all TEC/TC volumes will be soon available on the Web in ready-to-access form through IEEE Xplore and the CSDL; you will be able to appreciate first hand the tremendous changes that computing in general and TC in particular have undergone over more than five decades. Through its distinguished history, TC has grown from a publication originating from a dedicated pioneer Professional Group of the IEEE to a monthly publication with an impressive array of technical coverage by worldwide authors. As for the immediate past, 2007 has been yet again an exciting year; in this respect, I am very proud to announce the following milestones as significant accomplishments (all data is as of 2 October 2007, the date of writing this communication):

    1. IEEE TC is now the peer-reviewed journal with the highest impact among archival publications in the "computer systems" topical area (as indexed for 2006-2007 by ISI).

    2. For TC over the last 12 months to date as reported through Manuscript Central, the average elapsed time (in number of days) from submission to first decision is now 110, while the average reviewer turnaround time (also in days) for an initial submission is 47. These figures continue to show improvement over previous years; again the dedication of all Associate/Guest Editors and reviewers is gratefully acknowledged.

    3. The number of journal articles submitted to IEEE TC in 2007 has soared: From 1 January 2006 to 31 December 2006, TC received 491 submissions; from 1 January 2007 to 2 October 2007, TC has received 508 submissions. By 31 December 2007, I am expecting to have in excess of 600 submissions, a number that would represents an absolute record for TC.

    4. As per the Computer Society's report, TC has the highest penetration among all IEEE CS transactions for organizational subscriptions (such as libraries), a further sign of its extensive distribution and excellence.

In 2007, TC published two Special Sections featuring focused topical coverage, which (inclusive of Guest Editors, GE) were: Nano-Systems and Computing (GEs: Drs. DeHon, Lent, and Lombardi) and Emergent Systems, Algorithms, and Architectures for Speech-Based Human Machine Interaction (GEs: Drs. Capobianco, Deng, and Makino). I am deeply thankful to all of the Guest Editors for an exceptional job that, as always, has been accomplished in a timely and professional manner.
For 2008, the following Special Sections are planned and currently in different stages of progress: Networks-On-Chip (GE: Dr. Marculescu), Computer Arithmetic (GEs: Drs. Kornerup, Montuschi, Muller, and Schwarz), Programming Models and Architectures for Embedded Systems (GEs: Drs. Shukla and Talpin), and Special-Purpose Hardware for Cryptography and Cryptanalysis (GEs: Drs. Geiselmann, Steinwandt, and Koç). I strongly encourage prospective authors to periodically check the Web page of IEEE TC as well as the last page of a paper-printed issue for announcements about Calls for Papers as related to future Special Sections.
Also, I would like to take this opportunity to address some recurring inquiries that have often been encountered in the referee/decision process. Acceptance for publication in TC is highly competitive; after an initial comprehensive review process, only those manuscripts whose reports are substantially positive (albeit still lacking an overall consensus among referees) are allowed to continue for an additional round of reviews (either as a major or a minor revision). If strongly conflicting reports are received in the first round of reviews, an Associate Editor can now submit a recommendation that a manuscript should be "Revised and Resubmitted" (R&R). If the authors elect to submit a revised version under R&R, every effort will be made by me to reassign it to the original AE; however, please be aware that this may not always be possible (in some cases, the AE may have retired from the Editorial Board). Also, as per its mandate, the scope of TC is to publish papers whose contents balance theory and practice in computer engineering and science; hence, a R&R may also reflect such a type of deficiency in content. In essence, while R&R may come as a disappointment, it provides authors with detailed feedback by which manuscripts can be improved in a timely manner. Moreover, there is a no need to emphasize that TC has a unique scope in its mission, namely, to address theoretical and practical aspects of different areas as reflected by reader interest and a wide distribution to researchers, developers, technical managers, and educators in the computer field. I am personally committed to seeing that published articles reflect the highest quality while comprehensively meeting the scope of TC.
An archival journal such as TC heavily relies on a dedicated Editorial Board to meet its professional objectives. The appointment terms of the following Associate Editors expired during 2007: Drs. J. Becker, B. Bose, S. Iyengar, Ç.K. Koç, D. Pradhan, M. Sarrafzadeh, and M. Schulte. On behalf of the IEEE Computer Society, I thank them for their outstanding service to the learning community-at-large. I look forward to their continued involvement as contributors to manuscripts for TC.
Since June 2007, the following Associate Editors have been appointed to the Editorial Board of TC; their biographical notes can be found in the next few pages of this issue: Drs. C. Bolchini, G.A. Constantinides, S. Fahmy, K. Ghose, V.C.M. Leung, J.C.S. Lui, I. Markov, S. Olariu, S.H. Son, and S. Tragoudas.
As I start my second year as EIC, I look forward to your recommendations and suggestions, whether to propose a Special Section or to inquire about the status of your manuscript or just to let me know whether TC is meeting your expectations. In any circumstance, do not hesitate to contact me.
Truly yours,
Fabrizio Lombardi
P.S. I would like to acknowledge the invaluable help of Drs. C. Metra and P.
