| Summary: On the basis of a study of the selection of research subjects in the field of forest operations, of the research subject selection criteria, and an analysis of the structure of works published in the 1940-1990 period, the following conclusions can be drawn: Considerable mistakes are made when research topics are being selected, no matter how experienced the researcher is. The results of these mistakes are an unnecessary repetition of discoveries that have already been made, the unusability of the results of the research, increase in costs and reduction of the efficiency of scientific work. A scientific research subject can be constituted by all the factors of the operational and productive processes, their mutual inter-relations, factors from the environment and their effect on forest operations. The list of factors of forest operations that can form research topics is an open one. It is constantly being added to an expanded. There is no reason ever to expect a final version of this list. During research into forest operations, as in science in general, there is still an enormously spacious expanse of "no-man(s land". There are innumerable unknown "patents" of nature waiting to be discovered. This is very challenging for researcher, research institution and investor. Research topic selection is done by the researcher or research team, the scientific institution and the investor. All of them are interested in and responsible for the success of the scientific research. Research subjest selection criteria are related to the amount of research done on the problem, the aims ot the research, the creative inspiration of the researcher, the interests of the investor, the support for and conditions of research. The number of scientific papers published is used in science as an indicator of the development of scientific disciplines and of science as a whole. The number of papers in the area of forestry underwent a fall in the 1940-1945 period. In the 1945-1990 period it has been constantly on the rise, the growth being most marked in the 1945-1960 period. In the next decade it is to be expected that the growth of scientific research in forestry will be similar to that of the present decade. The structure of forest operation research subjects shows that there are important differences among research subject groups. The most papers have been publiced about forest work study, planning and control of forest operations. During the 1941-1990 period, the number of works published in individual groups increased by four to six times. The relations among individual research subject groups and their trend in the 50 year period can help to provide an estimate of the development of research into forest operations in the decade to come, to establish priorities and to select research topics.
