The 1981 Articles Nlost
Essays of an Information Scientist, Vol:6, p.373-383, 1983 The Number Current Contents, #46, p.5-15, November 14, 1983 1981 Articles Nlost Cited in 1981 and 1982. 2. Physical Sciences 46 November ThM is the latest in a series of essays in which we examine papers that become highly cited shortly after publication. Presumably, papers which have an immediate impact upon the research community, as indicated by rapid citation, point to “where the action is” in science. In this essay, we list those 1981 papers in the physical sciences which were among the most cited in 1981 and 1982. Recently, we published the comparable list for the life sciences. I Table 1 presents the 101 papers in thk study. They are listed alphabetically by first author, rather than by number of citations. The purpose of this arrangement is to inhibit invidious comparisons among papers on the basis of citation frequency. Of course, these papers are not necessarily the “best” research. Many seminal papers not listed here will eventually be highly cited. However, the evidence is clear from earlier studies that most of the papers we do detect by thk “early warning system” prove to be classics. And they persist as core papers in the research fronts they help to identify in the first place. Most of the 4,000,000 papers and books cited in Science Citation Index@ (SCP ) each year receive one or two citations over a two-year period. However, the papers in Table 1 received an average of 41 citations: eight in 1981, and 33 in 1982. The most-cited paper received 92 citations, while the least cited received 30. As with the 1981 life sciences papers, 1 we have chosen not to group these pa- 14,1983 pers under traditional disciplinary subject headings. Such headings are at times arbitrary, and always subjective. Instead, we used the same automatic class~lcation scheme which helps us identify thousands of research fronts each year by processing SCI. Briefly, a research front is a group of current papers which cite a smaller group of objectively determined core papers identified by a single-link, co-citation clustering routine. I have described co-citation clustering previously.z research Last year, we introduced fronts as a new way of searching our index to Scient~ic Reviews m (Z.SR‘“).s Eighty-three of the papers in Table 1 have already been incorporated into the core literature of ISR research fronts. Table 2 lists the names and numbers of research fronts which are those represented by at least two papers in this study. The numbers of the relevant research fronts in Table 2 follow the author addresses in Table 1. Four of the papers identfiled as core papers in ZSR research fronts are also core papers for research fronts in 1S1/ GeoSciTech ‘M, our onliie data base covering the earth sciences. Of these, three appear in research front #81-0986, “Observation of plasma waves near Saturn.” The other paper appears in research front #81-0803, “Electrostatic shocks and auroral particle acceleration. ” An additional four papers in Table 1 cite into one or more of the cores of various research fronts, including one pa373 Tafda 1: The 1981 physical sciences articles most cited in 1981-1982. The authors’ addresses follow each citation. Code numbers indicate the ISR ‘n research front specialties for which these are core papers.

Onehas six authors, three have seven authors, and two have eight. One paper each lists 12, 13, and 14 authors, while three papers have 16 authors. Onepaper each lists27 and66 authors. The paper with the most authors has 67. Thk is not unusual for physics. In our study of the most-cited physical sciences papers of 1980,4 one paper had 86 authors. Most such papers involve experiments with huge particle accelerators. Whale it is true that an enormous collaborative effort is involved in these experiments, it is hard to believe that so many individuals merit full authorship, In the past, I have called for reforms in thk areas Most contributors should receive credit in an acknowledgment. Current practices only pollute the bibliographic archives. Ninety-two authors have more than one paper listed in Table 1. C. S. Jacobsen, G. Senjanovi6, and E. Witten each have three papers. K. Bechgaard has five papers in Table 1. The papers in this study were published in 30 journals, listed in Table 3. Just six journals published more than 60 percent of the papers. They are: Phy.rical Review Letters (19 papers), Physics Letters B (12), Nuc/earPhysics B (9), As- 379 4 16 2 2 3 6 2 69 24 17 10 16 15 26 trophysical Journal (8), Journal of the Amen”can Chemicai Society (7), and Science (7). These journals consistently publish a high proportion of papers in these studies. In fact, Physical Review Letters has topped our list each year since we began thk series by examining the most-cited physical science papers of 1976!6 This also reflects the need for rapid communication in a field where preprints are common. The authors in this study are affiliated with 118 institutions in 18 countries. Table 4 lists these institutions in descending order by the number of times they appear in Table 1. Sixty-three are located in the US, about the same as in our study of the 1980 papers. This represents a signtilcant increase over the US totals for 19787 and 19798 which were 44 and 48, respectively. However, the actual number of papers in these studies produced by US institutions has been declining in recent years. For example, authors from US institutions produced 88 papers in our study of 1979 articles. For 1980 this dropped to 73 and for 1981 it is 67 papers. By the way, it is an important commentary on the international role of American and other scientific journals to see that three papers from the USSR are inchrded in this study. Table 3: The Xl journals represented on the list of the 101 1981 physical sciences papers most cited in 1981-1982. The numbers in parentheses are the impact factors for the journals. ( 1981 impact factor equals the number of citations received by 1979-1980 articles in a journal divided by the number of articles published by the journal during the same period. I Data were taken from the 1981 JCI? ‘n. The figures a~ the right indicate the number of papers from each journal which appears on the list. China, Poland, and the USSR each have one. Incidentally, the People’s Republic of China was also represented by one institution in our look at the most-cited physics papers of 1979.s Perhaps the appearance of an institution from there in the present study is a harbinger of things to come. Haward University was listed 12 times on Table 1, more than any other institution. Stanford University was represented 11 times. The University of California was represented nine times, while CERN was represented only three. In our 1978 study, CERN was represented 19 times. Table 5 lists the national affiliations of authors in this study. As I mentioned earlier, 67 of the 101 papers in thk study had authors from the US. Seventeen of these were coauthored with scientists from Canada, Denmark, France, FRG, Israel, Italy, the Netherlands, People’s Republic of China, Poland, Sweden, Switzerland, and the UK. Without exception, the papers were written in English. The list of research fronts in Table 2 provides a good indication of some of the hot subjects of current interest to physical scientists. In fact, four research fronts are represented by six core papers listed here. Six papers are core to research front #83-0030, “Dynamic aspects of lattice Interactions between gauge theories.” subatomic particles are described in terms of gauge theories. Five of the highly cited papers in this research front apply so-called “Monte Carlo methods, ” a statistical technique, to the study of “strong force” interactions, The strong force, one of the four fundamental forces of nature, is what holds the nucleus of an atom together. The list includes six papers in research front #83-0558, “Organic superconductors.” Superconductors are substances which, when cooled to extremely low temperatures, lose virtually all resistance to the flow of electricity.

This research front includes the second most-cited paper, a single author work by E. Witten, Princeton University, New Jersey. Witten’s paper was cited 87 times during the two-year period. A check of the 1983 SCI shows that it continues to be heavily cited. Research front #83- 1234, “Voyager 1 and Voyager 2 observations of Saturn and Titan and analysis of rings of Saturn, magnetosphere and atmosphere,” contains six papers in thk study as core documents. Papers reporting observations of the Voyager space probes have appeared in these studies before. This research front contains the third mostcited paper in thk study, that by B.A. Smith, University of Arizona, Tucson, and colleagues. The paper reports on a number of observations of the planet Saturn, its rings, and moons. It was cited 80 times during 1981-1982. The most-cited paper in this study, a single author work by A .H. Guth, Stanford Linear Accelerator Center, California, received 92 citations during the twoyear period, It is one of the core papers in research frent #83-0029, “Phase transitions in the early universe and the inflationary universe scenario. ” Guth’s paper advances a proposition regarding the temperature of the universe early in its hktory, and discusses its implications for the so-called “big bang” theory of creation. It has already been cited 43 times in the first six months of 1983. Tied for the second most-cited paper in this study is a lengthy review by P. Langacker, University of Pennsylvania and Stanford Linear Accelerator Center, of various unified field theories. It was published in Physics Reports-Revie w Section of Physics Letters, which is published by the North-Holland Publishing Co. The paper received 87 citations in 1981-1982.

K. Bechgaard, University of Copenhagen, Denmark, appears on five of the papers in thk group: twice as a first author, and three times as a secondary author. Six papers in Table 1 are core documents for research front #83-0885, “Supersymmetric grand unfiled theones.” “Supersymmetry” is the label given to one of several theoretical approaches 382 The fourth most-cited paper in Table 1 describes a new method developed by M. Barber and colleagues, University of Manchester Institute of Science and Technology, England. The method improves the results of mass spectronomy performed on nongaseous substances. It received 77 citations during the two-year period. This concludes our study of the mostcited physical sciences papers of 1981. This series will continue next year when we identify the most-cited papers of 1982. Remember that we treated chem- istry separately in a study of the 1980 papers.g We will continue to do so for 1981, although several chemistry papers were cited frequently enough to meet the threshold for this study. ***** My thanks to John Dale and Tom Di Juliafor their help in the prepamtion @l@l 1s1 of this essay.
