Reference and information services are considered an important activity of a modern library. This comprehensive and student-friendly book discusses in detail different types of information and reference sources and services, such as encyclopaedias, directories, yearbooks, dictionaries, geographical sources, biographical sources, statistical sources and handbooks. The book is organised into four parts. Part I deals with various types of information sources such as documentary and non-documentary sources. Part II discusses different types of reference services, organisation of reference section and the role of the librarian in the digital age. Part III describes the wide range of information service such as Current Awareness Service (CAS) and Selective Dissemination of Information (SDI). Part IV provides an overview of important information systems such as National Information System for Science and Technology (NISSAT) and International System for Agricultural Science and Technology (AGRIS). The book is intended for the undergraduate and postgraduate students of library science. Besides, it will also be very useful for librarians, information scientists, and information professionals. Salient Features Deals with both theoretical and practical aspects of information sources and services. Discusses various types of information sources and services keeping in view the latest trends and developments in the field. Presents the concepts related to information sources and services in a systematic and accessible way.

The Workshop Proceedings reflect problems of advanced geo-information science as far as they are specifically concerned with the maritime environment at large. The Proceedings incorporate papers presented by leading scientists researching in the considered professional area and by practitioners engaged in GIS and GIS applications development. They pay close attention to the problems of scientific and technological innovations and the ensuing opportunities to make seas safer and cleaner. Furthermore, they periodically measure the ground covered and new challenges with respect to economic and shipping trends as related to Artificial Intelligence; GIS ontologies; GIS data integration and modelling; Underwater acoustics; GIS data fusion; GIS and corporate information systems; GIS and real-time monitoring systems; GIS algorithms and computational issues; Novel and emerging marine GIS research areas; Monitoring of maritime terrorist threat; Maritime and environmental GIS; Navigation-based and maritime transportation GIS; Human factors in maritime GIS; Coastal and environmental GIS.

Mobile Cloud Computing: Models, Implementation, and Security provides a comprehensive introduction to mobile cloud computing, including key concepts, models, and relevant applications. The book focuses on novel and advanced algorithms, as well as mobile app development. The book begins with an overview of mobile cloud computing concepts, models, and service deployments, as well as specific cloud service models. It continues with the basic mechanisms and principles of mobile computing, as well as virtualization techniques. The book also introduces mobile cloud computing architecture, design, key techniques, and challenges. The second part of the book covers optimizations of data processing and storage in mobile clouds, including performance and green clouds. The crucial optimization algorithm in mobile cloud computing is also explored, along with big data and service computing. Security issues in mobile cloud computing are covered in-depth, including a brief introduction to security and privacy issues and threats, as well as privacy protection techniques in mobile systems. The last part of the book features the integration of service-oriented architecture with mobile cloud computing. It discusses web service specifications related to implementations of mobile cloud computing. The book not only presents critical concepts in mobile cloud systems, but also drives readers to deeper research, through open discussion questions. Practical case studies are also included. Suitable for graduate students and professionals, this book provides a detailed and timely overview of mobile cloud computing for a broad range of readers.
