摘要：HELEN L. BROWNSON has recently published an excellent review, "Research on Handling Scientific Information" (1), containing brief descriptions of current studies on use of library materials including scientific journals, and in 1959 Elin Tornudd put out a most helpful annotated bibliography of the use of scientific literature (2) listing upwards of a halfdozen articles on biological and medical journals. Studies not included in T6rnudd's paper are William D. Postell's report in 1946 on the use of 11 physiological journals at the Louisiana State University Medical Library (3), and a study of 400 heavily and moderately used journals in the Yale Medical Library carried out late in 1952 (4). Subsequently, studies have come from the Library of the College of Physicians of Philadelphia (5) that included a list of its "50 most requested titles," and from the Mayo Clinic Library giving 209 titles of the most heavily used unbound issues for 1954 to 1956 (6).
