A study reported in 1974 of the World List of Scientific Periodicals (4th edition and 1968 supplement) showed thatthe number of journals in the field of microbiology increased as follows:

                1900                                19 journals

                1920                                68 journals

                      1940                               160 journals

                1960                              286 journals

                      1968                               327 journals                     (Source)

A study reported in 1974 of citations in articles listed in the Annual Review of Microbiology (vols. 22-24, 1968-70) involving 624 titles and 10,408 citations showed thatthe 10 most cited journals were:

                Journal of Bacteriology

                Proceedings of the National Academy of Sciences, U.S.A.

                Virology

                Nature (London)

                Journal of Molecular Biology

                Journal of Biological Chemistry

                Biochimica et Biophysica Acta

                Journal of General Microbiology

                Biochemical and Biophysical Research Communications

                Science (New York)                    (Source)

        Ibid…. showed thatthe 8,051 citations of the 141 most cited periodicals fell into 4 main subject areas (out of 23 categories): biochemistry (23.6%), microbiology (22.4%), science—general (18.1%), and virology (10%).                    (Source)

        Ibid…. showed that, of the 141 most cited journals, the top 3 language formats were English (83 or 58.87% of total journals); multilingual, involving English, French, or German (27 or 19.15% of total); and multilingual, involving 4 languages of which English, French, and German were 3 of the languages (9 or 6.38% of total).                  (Source)

        Ibid…. showed thatthe 3 main countries of origin of the 141 most cited journals were United States (54 journals accounting for 58.03% of total citations), United Kingdom (29 journals accounting for 22.24% of total citations), and Germany (11 journals accounting for 4.16% of total citations). However, the Netherlands with only 5 journals accounted for 4.92% of the total citations.  (Source)
