Most Frequently Cited Phytopathology Journals
Institute for Scientific Information
At the last annual meeting of The American Phytopathological Society, I had the honor to address your members on the subject of information retrieval. In the course of my remarks, I mentioned a study conducted at the Institute for Scientific Information, which showed how our Science Citation Index ® data base could be used in organizing small library collections.
From the SCI ® we have compiled a monumental Journal Citation Index , which shows citation relationships between thousands of journals. For example, the JCI shows that in the last quarter of 1969, out of approximately 1,000,000 citations, the journal Phytopathology cited the following list:
Phytopathology (Self-Citation) 822 Plant Disease Reporter 119 Virology 80 Canadian Journal of Botany 51 Plant Physiology 51 American Journal of Botany 47 Nature 46 Annals of Applied Biology 41 Annual Review of Phytopathology 38 Phytopathologische Zeitschrift 37 Journal of Agricultural Research 36 Science 30 Journal of Bacteriology 22 Journal of Biological Chemistry 22 Mycologia 20 Agronomy Journal 19 Journal of General Microbiology 19 Annual Review of Plant Physiology 17 Australian Journal of Biological Sciences 15 Transactions of the British Mycological Society 15 Journal of Economic Entomology 15 Soil Science 15 Crop Science 14 Journal of Agricultural and Food Chemistry 14 Annals of the Phytopathological Society of Japan 13 Sewage and Industrial Wastes 12 Biochimica Biophysica Acta 11 Canadian Journal of Microbiology 11 Canadian Journal of Plant Science 11 Nematologica 11 Botanical Review Review 10 Methods in Enzymology 10 All others (731 publications including books and other known journal items) 1,148 Total 2,842
It is worth noting that not a single member of the audience at the APS meeting could guess in advance that the third most frequently cited journal in this field is Virology . It is especially noteworthy that the analysis clearly distinguishes the journal Virology from the Journal of Virology as the journal of major importance to plant disease researchers-a decision that might be very difficult to make without such data.
In contrast to the list of journals cited by Phytopathology there follows the ranked list of source journals in which it was cited:
Phytopathology (Self-Citation) 822 Annual Review of Phytopathology 291 Transactions of the British Mycological Society 46 Canadian Journal of Botany 42 Mycologia 30 Virology 28 Annals of Applied Biology 19 Botanical Review 18 Canadian Journal of Microbology 17 Canadian Journal of Plant Science 15 Hilgardia 14 Theoretical and Applied Genetics 14 American Potato Journal 12 Journal of Economic Entomology 12 Science 10 All others (109 journals) 309 Total 1,713
As a result of such analyses, we added Plant Disease Reporter to our SCI coverage, an oversight that is comprehensible only if one considers that at ISI we deal with thousands of journals from all fields of research.
If any of your readers know of similar studies for phytopathology literature, I would be grateful to hear from them.
