P.04 - Editorial Notes

PERSONAL

As you open up this month's issue, you will notice that there has been a drastic change in the make-up of the pages. The actual size of each page has been cut down quite a bit. We doubt if it is in any way an improvement, but it is made necessary by the need for conserving stocks of paper, thereby indirectly saving the dollar exchange, thus to allow the purchase of American aeroplanes for the War effort. Regulations have been introduced with a view to cutting down the amount of paper used by about 35%. From a glance at the regulations, it is not clear whether the actual number of pages has to be cut down or whether the saving can be made by any other method which will allow the best possible production to be made without using more than 65% of the paper used previously. We have gone into the matter carefully and we feel sure that the best possible way we could cut would be to cut down the margins, spaces between columns and so on, thereby allowing us to continue to give as much technical information as possible. And so we have this new style, which may not be artistic, but we feel sure that our readers will appreciate that the paper saving is being made and yet the editorial content is being retained, together with the good quality paper which allows the circuits to be reproduced clearly and the photographs to be printed in a way which makes it possible for the experimenter to see just how the original sets were built. Even if the way we have made the saving does not fulfill the requirements of the regulations to the letter, we have an easy conscience, as we feel that we have "done our bit" in making the saving. We also feel fairly safe in the thought that the authorities must surely recognize that a technical journal, devoted to improving the public's knowledge of radio communication, is a little different to a magazine devoted to the publication of doubtful jokes, or love stories. Actually the regulations do not come into force until the next issue, but if the saving of paper is important we felt that we should start immediately. Before the next issue is brought out there may be alterations or amendments to the regulations, but readers can rest assured that, even if we have to save paper, we will maintain our editorial policy to the best of our ability.
