摘要:

AbstractCurrent interdisciplinary information in science and technology was studied in connection with some aspects of the integration of the sciences. The investigation was carried out by combination of research methods such as testing, surveys, and source analysis. The experimental method for tracing relevant publications unknown to the user is described. The results of questionnaires sent to 432 specialists in 16 countries are presented. Some features of the integration of the sciences were investigated together with the specific information demands which they provoke. It is shown that these demands cannot be satisfied within the limits of discipline‐oriented information systems. Particular attention is given to information problems of small developed and developing countries. The efforts of these countries must concentrate on the compilation of information indexes on complex and interdisciplinary problem

摘要:

AbstractDifferential demand for use among the items in an information store is a necessary condition for management of the store. Using bibliometric techniques for determination of the distribution of demand, the hypothesis of hyperbolic distribution, and an index of differential demand are developed.

摘要:

AbstractThe distribution of use of items in a large information store is examined. The findings suggest that a simple exponential distribution is inadequate and that a multi‐factor exponential model describes the process of obsolescence more precisel

摘要:

AbstractBased on earlier studies by the author relating to differential demand among items in an information store and to the relation of demand to age of material, this article undertakes to develop an empirical model for predicting the size of an information store necessary to satisfy specified levals of demand. Amodus operandifor selecting items for retirement or removal with the least adverse impact on effectiveness of the store is suggested.

摘要:

AbstractA recently suggested method for the automatic indexing of full text is applied to extracts from the Brown Corpus. Scientific and technological extracts are found to give rise to a much larger number of index terms than humanities and social science extracts. These results would appear to arise from differences in the word frequency distributions for each type of subject.

摘要:

AbstractSecondary access services for the humanities have been in existence since 1910 and six of these indexes are also now available for online searching. Profiles of these services are drawn from information supplied either by their editors or from available literature. The evolution of some of these services from print to online availability is discussed as are the user and database characteristics which make humanists reluctant to use these services in their machine‐readable forms. The resulting lack of use of humanities databases is discussed as are the marketing responsibilities of both vendors and producers. The current state of the humanities database producers' view of themselves as a unique group with unique problems and concerns and current trends toward standardization in humanities databases are reviewe

摘要:

AbstractThis article provides a broad overview of the development of abstracting and indexing services in science and technology during the last three and one‐half decades. It identifies major trends that have clearly affected individual producers, services, and the field as a whole. These trends include the changing national priorities, the new technologies, and the growing importance of marketing. Change, transformation, and survival are keywords in the discussio

摘要:

AbstractSecondary access services available to American social scientists include bibliographies for the academic disciplines and a large variety of specialized services for subdisciplines and interdisciplinary fields. Nearly all originated during three decades of intensive development between 1950 and 1980. Coverage of journal literature is more extensive than coverage of monographs and data sources. Clearer differentiation among services in overlapping fields is needed. The transition from paper‐based to computer‐based services offers many possibilities for improved access to the literature, but difficulties attributable to intellectual and organizational characteristics of the social sciences may be relatively unaffected by technological cha
