j. Cosmet. Sci., 51,401 (November/December) Letter From the Editor To Our Readers: With this issue of the Journal, I come to the end of my tenure as editor. The last three years have been exciting and productive for the Journal. We have been able to maintain a timely publication schedule. At the same time, the quality of our manuscripts is as high as ever and the number of papers submitted is slowly increasing. I have been especially impressed by the quality and number of papers relating to hair science and technology. Two of the goals I set when I assumed the editorship were to increase the breadth of coverage of the Journal and to encourage as wide an audience as possible. We are making significant progress on both fronts. Within the last month we received notice that, for the first time, the Journal's articles are going to be included in Index Medicus, making them accessible globally to researchers, teachers, and students who might not otherwise be aware of them. I'd like to express my appreciation to the members of the Editorial Advisory Board for their guidance and help in settling disputes between reviewers, and especially to the associate editor, Linda Rhein, who will be taking over as editor in 2001. I'm also grateful for the administrative assistance supplied by the office of the Society, especially Doreen Scelso, who has done an admirable job of keeping track of papers, corresponding with authors, and nagging forgetful reviewers. Speaking of reviewers, they are the unsung heroes of the entire publication process, giving freely of their time and expertise to help authors publish the very best manuscripts. Reviewers, thank you! Finally, best wishes to Linda and the board in the years to come. Joel L. Zatz 401
