The Future of Faraday Transactions The Faraday Editorial Board has recently given careful consideration to the future of Faraihy Transactions. As a result of this review a number of very important changes will be made h m January 1990 to the appearance, the organisation, and the publishing of the Transactions. We believe that these will further enhance the reputation of the Transactions and increase their attractiveness both to authors and to readers. One of the most obvious changes is that the rather arbitrary separation of the Transactions into two parts will cease. From January 1990, there will be a single journal entitled Journal of the Chemical Society, Far& Transactions, which will appear 24 times a year. The appearance of the journal will be improved markedly by the introduction of new covers, higher quality paper and a more modem, two-column A4 format.The rewLification of the two parts of the Transactions with issues published every two weeks will increase the flexibility of our operations, and the publication of Special Issues, such as Faruday Symposia, will cause virtually no delay to regular papers. Achieving short ‘times to publication’ is viewed as our highest priority. Since the move to the new Cambridge office very considerable improvements have been made in this respect. I am confident that with the journal in its new form we shall achieve publication times of four months after acceptance for normal papers. In addition, we are to introduce a letters section to be called Faraday Communications. Faradby Communications should describe important new advances in no more than 1600 words and we shall guarantee a publication time of 12 weeks, as long as there are no delays due to referees’ comments.It will be possible to submit Faraday Communications via a member of the new International Advisory Editorial Board. The composition of this board will be announced in a forthcoming issue. Faraday Editorial Board is very happy to announce the appointment of Dr Peter S a m of the University of Nottingham as Scientific Editor from 1st October 1989. Without in any way weakening our commitment to those areas of physical chemistry in which the Tranractions have been particularly strong, Dr Sam will be especially committed to attracting high-quality papers in experimental and theoretical chemical physics.Finally, the Editorial Board would like to place on record its appreciation of the huge contribution that Dr David Young made to the development and success of Farday Transactions and Faraa‘uy Discussions during the 19 years that he was Scientific Editor.
