This comprehensive introduction gives basic how-to information on the use of online systems, discusses topics for which there are no accepted paradigms, and presents alternative points of view within a framework of previous research. Expanding on their immensely popular and critically acclaimed first edition, the authors have added extensive new material addressing Internet search and retrieval techniques as well as the more traditional Dialog and Lexis-Nexis services. Это и многое другое вы найдете в книге Online Retrieval: A Dialogue of Theory and Practice (Geraldine Walker, Joseph Janes, Carol Tenopir)
