rately is never easy, as your friendly w e a t h e r m a n will freely ad mit. F o r scientific journalists, such prognostication is equally fraught with pitfalls; however, sober reflec tion on a few current trends m a y pay handsome dividends later. Most p r i m a r y scientific research journals, such as Analytical Chem istry, have been faced recently with falling advertising revenues and subscription . ts and concomitantly increasing pu ication costs. {Ana lytical Chem try now appears to have turned 1 3 corner on advertis ing revenues, ί the number of ad vertising page, s up over last year, albeit only slij. tly, for each 1972 issue to this date.) Even journals which carry little or no advertising have been caught in the economic crunch as the number of qualified articles submitted to t h e m grows while page budgets fall or remain constant. Only medical journals seem to be immune t o this situation. (Perhaps there is a lesson in t h a t fact.) Some journals have found themselves forced into accumulat ing rather large backlogs of ac cepted, b u t unpublished, articles —a situation bemoaned by all but difficult to alleviate. (Fortunately, Analytical Chemistry does not yet suffer seriously from such a prob lem.) Perhaps scientific journals would be well-served by what the government likes to call a "costbenefit" analysis. Scientists would generally agree t h a t the objective of a primary re search journal should be the prompt publication of new information which has had a careful, critical re view. A number of circumstances can interfere with the orderly pre sentation of such material ; perhaps the two most important of these might be termed "prior publication" and "multiple publication." I n the first case, Analytical Chemistry's, policy has been and remains t h a t material which has been previously

Editors' Column
published (200 copies or more) a n d / o r abstracted in Chemical Abstracts is not acceptable. Professor Laitinen spelled out this journal's policy on prior publication in detail in an editorial several years ago [Anal. Chem., 39, 553 (1967)]. T h e question of multiple publication is more subtle, but it boils down to the fact t h a t simultaneous or consecutive publication in the same journal or in different journals of multiple applications of similar techniques is inadvisable. Such publication does little to enhance the reputation of any journal or author, especially if the techniques are of limited appeal or utility, and it does t a k e up valuable space which could be used to erode a growing backlog of more original work. P e r h a p s the "publish or perish" u l t i m a t u m , still prevalent a t m a n y universities in determining the fate of young professors, is p a r t l y responsible for the persistence of multiple publication. T h e policy of "publish or perish" places a burden on journal editors, as well as on junior faculty m e m b e r s ; it is probably time to reconsider this policy carefully in view of recent developments. T h e central issue in the question of where the future of scientific journals lies is really quite simple. T o remain economically viable, journals cannot publish great q u a n tities of similar material of limited appeal. If this practice proliferates, advertising in journal pages will slacken further, subscriptions will continue to fall off, and the most i m p o r t a n t objectives of scientific journals will not be wellserved. T h e staff of Analytical Chemistry is eager to continue providing our readers with a convenient source of new and interesting information of high quality, and with the help of our skillful and seemingly tireless reviewers, we will m a k e every effort to do so. B u t our ultimate chances for continued success arc, to a large degree, up to the research scientists who submit p a pers to us for publication. Alan J. Senzel
VARIAN'S NEW $10,700 60-MHz NMR SYSTEM GIVES YOU HIGH PERFORMANCE EXCELLENT VERSATILITY..
,AND A CHOICE Varian Anaspect's new EM-360 has a guaranteed resolution of 0.6 Hz and a guaranteed sensitivity of 18:1 using 5-mm sample tubes. A variety of operating parameters makes the system easy to operate with a maximum of performance flexibility. And it's priced lower than any other 60-MHz NMR system suitable for both teaching and research. Look at these outstanding operating advantages. Continuously variable rf power allows full utilization of the six available sweep times. Six scale expansions let you make the best choice for your application.There's an exclusive end-of-sweep control; a standby lock; a large, flexible XY recorder; a built-in integrator; an accessory oscilloscope (optional). And the instrument's design lets you add on other accessory modules of your choice as they become available. The EM-360 evolved from Anaspect's approach to economical manufacturing plus Varian's leadership in NMR. It's one of a unified line of products from Varian Anaspect. . . specialist in quality instruments designed to give you more data per dollar. So, if you're in the market for a low-priced NMR system with high performance, talk to the NMR specialist who gives you a choice. The versatile, new EM-360, or the even lower-priced 30-MHz EM-300. With 60-day delivery on 60-MHz systems. For bulletin, spectra, and locations where you can see an operating EM-360, contact your local Varian NMR representative. Or write Varian Anaspect, 611 Hansen Way, Palo Alto, California 94303.
