Information Technology, though relatively, a new stream is as vast as a sea. It's perhaps the most relevant and most applied among the disciplines, in currency, in the modern context. Further, it has earned new world order and the globalization.

In today's world, each and every awakened individual has to be fully aware of what Information Technology is all about. This exhaustive work is meant for the laymen and the students alike. It's an introductory volume and as well as a semi-text book, in itself.

Applications of Computer in Chemistry are now a part of curriculum in B.Sc. and M.Sc. classes of most of the Universities. This portion has been introduced by U.G.C. in the model course curriculum as well. The present book focuses on the use of this electronic machine in dealing with the problems of chemistry. Main attention has been focused on development of programming logic and technique particularly dealing with the problems of Chemistry which should be the most important part before actually writing any Computer program. Fundamentals of three languages viz. BASIC, FORTRAN and C-Language, have been included in this book. Most of the programs in this book are given in BASIC language as it is easy to learn and interactive too. Ample programs are also given in FORTRAN and C-Language. It is has been tried to include all the programs in this book with their outputs. Hope this book will serve the purpose and will prove to be useful for the students pursuing studies in Chemistry at B.Sc. or M.Sc. level.

CONTENTS
Introduction to Computers; Fundamental Concepts of Programming; Ms-Dos and its Use; Fundamentals of Basic Programming; Fundamentals of FORTRAN Programming; Fundamentals of C-Language; some Useful Programs in Chemistry; etc.

The present publication comprises three well-structured compilation to cover such crucial areas in the definition, development and design of library science and information technology, "Perspective and Profiles in Library Science and Information Technology", "Library Resource Development and Training", and "Library and information Science in Planned development".

This will certainly prove informative to all the concerned.

The modern library and truly professional librarian have both moved in tandem-from the card-index age to the electronic multimedia era of micro-film, CD-ROMs and Websites. In a true sense, the modern library is an active partner of giant of information technology and together they constitute a centre of knowledge and activity, research and learning that is global in its perspective and cosmic in its outreach. The present book contains well-researched articles, substantially based on the writings of eminent authorities in the field.

The main topics are: Librarianship and the Professional Librarian; Modern Documentation and Information Technology; The Computer in the University (A Discussion on Computronics and Practicable Applications); The Miniature Library: Microfiche Technology; Major Issues in Software and System Selection; Documentation and computer Output Alternatives; Major Issues in Serial Publications; Documentation of International comparative Statistics (International Organisations); Libraries and Scientific Literature: A Training Perspective; and Resource Sharing and Objectives. This will prove an asset to scholars and professionals in the field alike.
