This parameter and the costs of subscription are the basis for journal ranking and determination of the number of copies (to be bought).This method has been verified by the use of data from the SDI system exploited at Wrocław Technical University.Having compared the achieved results with the results of the simultaneously conducted questionnaire investigation, it has been found that there is a considerable degree of accordance between the results of journal acquisition planning based on the described method, and the demands of journal users.
