Abstract
Purpose
This paper aims to semantically linking scientific research events implied by scientific and technical literature to support information analysis and information service applications. Literature research is an important method to acquire scientific and technical information which is important for research, development and innovation of science and technology. It is difficult but urgently required to acquire accurate, timely, rapid, short and comprehensive information from the large-scale and fast-growing literature, especially in the big data era. Existing literature-based information retrieval systems focus on basic data organization, and they are far from meeting the needs of information analytics. It becomes urgent to organize and analyze scientific research events related to scientific and technical literature for forecasting development trend of science and technology.
Design/methodology/approach
Scientific literature such as a paper or a patent is represented as a scientific research event, which contains elements including when, where, who, what, how and why. Metadata of literature is used to formulate scientific research events that are implied in introduction and related work sections of literature. Named entities and research objects such as methods, materials and algorithms can be extracted from texts of literature by using text analysis. The authors semantically link scientific research events, entities and objects, and then, they construct the event space for supporting scientific and technical information analysis.
Findings
This paper represents scientific literature as events, which are coarse-grained units comparing with entities and relations in current information organizations. Events and semantic relations among them together formulate a semantic link network, which could support event-centric information browsing, search and recommendation.
Research limitations/implications
The proposed model is a theoretical model, and it needs to verify the efficiency in further experimental application research. The evaluation and applications of semantic link network of scientific research events are further research issues.
Originality/value
This paper regards scientific literature as scientific research events and proposes an approach to semantically link events into a network with multiple-typed entities and relations. According to the needs of scientific and technical information analysis, scientific research events are organized into event cubes which are distributed in a three-dimensioned space for easy-to-understand and information visualization.

Abstract
BOOKS are among the greatest and most wonderful achievements of human genius, they are also a powerful means of struggle for progress. The book accompanies man all his life; it is a creation of his brain and soul. It reflects the life of mankind and is the result of collective efforts of author and publisher, type‐setter and illustrator. But foremost a book is always and everywhere a social and political phenomenon. One of the most apt evaluations of the book was given by V. I. Lenin in 1917, when he was known to state to A. V. Lunacharsky, “The book is a great force indeed”.

Abstract
The paper attempts to provide an outline account of the development and context of scientific and technical communication during the twentieth century. The main channels and forms of communication are reviewed, and their changing contributions to the overall pattern of information flow. The ever‐increasing volume and diversity of scientific and technical information are emphasised. The paper concludes with some reflections on what may be learnt from this history.

Abstract
Argues that as the developed countries of the world that have embraced the electronic information revolution move ahead, most African countries, including Nigeria, are finding themselves increasingly isolated from the global Internet information system. Highlights the major factors inhibiting the utilization of scientific and technical information in the country and stresses that it is imperative to secure a means of keeping researchers abreast of developments in their fields for the purpose of advancing and diffusing knowledge. Recommends the establishment of a National Scientific and Technical Information Center to oversee the connection of Nigeria to the Internet. Describes the model for setting up such an institution.

Abstract
It is with some trepidation I introduce this subject before an audience with such a wealth of experience in scientific and technical information work, but I hope to hold your attention for the next forty‐five minutes as I try to evaluate the factors which, in my experience, have influenced the flow of information and, I hope too, to provoke some much needed thought on the problems that confront us all in this field today.

Abstract
Discusses the general principles for the management of scientific information. These include a broad definition of scientific and technical information, a proper regard for the aims and objectives which such information might serve and an awareness of the infrastructure prerequisites for the development of the efficient management of scientific and technical information. Such management systems are particularly essential in developing countries where most forms of scientific and technological information are in scarce supply. Provides a survey of the development of organizations and arrangements for the management of scientific information in Kenya as an illustration of some of these general principles.

Abstract
Following consideration of the central technical library services of the country, the Panel on Technical Information Services has reviewed other types of technical information services in the United Kingdom as a means of ensuring that technical information, whether recorded or unrecorded, is made available to everyone in need of it. The present report outlines some of the main considerations in the organization of a comprehensive national service of technical information and makes recommendations for improving the present service.

Abstract
In this talk, I propose to cover two areas of intellectual property. These are copyright and patents. I will examine both of these topics in regard to the provision of scientific and technical information and the development of a dynamic and growing electronic information industry. For I believe that any country that plans to have a healthy information industry requires strong and rigorously enforced patent laws, and strong and rigorously enforced copyright laws.

Abstract
An account is given of a national survey of staff employed on scientific and technical information work, carried out in the UK in the summer of 1965 by the Office for Scientific and Technical Information. Its prime purpose was to try to obtain some measure of the numbers of such staff and their educational background (including information work), in order to estimate future demand, and the educational requirements needed to ensure that information staff are adequately trained. Appendices set out the data obtained.
