During the last ten years, librarianship has developed enormously not only in its traditional areas but also into new areas involving completely new techniques and the uses of the equipment which has been developed to enable more work to get achieved with the minimum of extra manpower. The present title "Encyclopaedic Dictionary of Library and Information Science" has been an attempt to include the terms from all these fields. It is primarily a dictionary of library terms but also includes such subjects as printing, paper making, publishing, binding, illustration and applications of computers to library systems with which a librarian must be familiar for the performing his professional duties. The terms included in this dictionary have been restricted to those of a more fundamental nature and defined simply and without unnecessary technicalities. Wherever necessary, line diagrams have been included to illustrate the terms fully.

This work has been carefully compiled primarily for the use of students of librarianship who have always needed such a book of hand during their studies. It is anticipated that the book will be useful to university, college, public and school librarians besides that it will also find a place on the open shelves in reference libraries.

The present day knowledge or information-based society is making extensive use of information for all kinds of activities. It is the developments in communication technology, which took place since late eighties that provided an impetus to the use of computers in various segments of society and libraries, which literally caused revolution. Internet-based innovations and applications are emerging daily and end is not in sight. Information revolution is ultimately benefiting the whole world. This is happening because of increasing utilisation of computers and communication in every area.

Library and information science area has also gone tremendous changes. The present work truly encyclopaedic in nature encompasses a great treasure of terms and phrases, explained in simple and clear way pertaining to computer and library science. The information is gathered from authoritative sources as such the definitions and explanation is reliable and authentic.

Amidst the plethora of similar literature this dictionary is unique, amalgating the latest research and developments in the field. No doubt, the present endeavour will satiate the quest of one and all.

Encyclopaedia of Nanotechnology is one of its kinds in terms of coverage, scope, elaboration, usefulness and futuristic perspective. Nanotechnology is now a rapidly growing field of research and development that is cutting across many traditional boundaries. This technology has the ability to control or manipulate on the atomic scale. Nano is a prefix meaning one billionth (1/1,000,000,000). This is why; Nanotechnology overlaps with a wide range of the existing sciences. Subjects that seem at present to have the most direct and constructive involvement with Nanotechnology are: Optical and Quantum Physics; Molecular Biology; Biomedical Engineering (through genetics and Microbiology); Electrical Engineering (through MEMS systems); Software Engineering (through AI, Communication and Information Systems). The applications of nanotechnology are near limitless, but the main focus seems to be on its use in medical applications. That seems to be what's driving the research, since it would give us to opportunity to cure most diseases, even possibly eliminating the concept of natural death. There are so many other applications, however, ranging from mundane to incredibly profound. Other applications include ultra-fast & high memory capacity computers, highly advanced communication systems, advanced display technology, advanced biological imaging, stem-cell engineering, medical diagnostic tools, sensors for airborne pollutants energy storage materials, photovoltaic cells, fuel cells, polymer nanocomposites, super-tough nanocoatings, landmine detectors, and thousands more. Nanotechnology has, therefore, become the hottest topic of discussion in the scientific world, media, government circles and corporate circles. Although it is a field that has already seen its share of hype, there is a general consensus that over the long term, nanotechnology is likely to reconfigure everything.

Education is a vast discipline and Teachers' Training is a vital part of it. The responsibilities of the educationists and educators are focused on the task of providing better training to the future teachers for their better learning and proper development. Needless to say that this responsibility can only be exercised, if the trainers are equipped with the required knowledge of the subject concerned. That's why it becomes essential for making adequate provisions for each course to the student-teachers or teacher trainees. The present series is designed for providing a solid workable base for all course-papers. It has been prepared strictly according to the syllabus of the B.Ed. class, prescribed by the UGC for different universities. The present book viz. Modern Teaching of Computer Science covers all aspects of teaching computer science in the present day context.
