Cassell (master's of library and information science program, Rutgers U.) and Hiremath, a librarian, detail the skills needed by reference librarians. They treat reference transactions as a process of understanding a question, identifying best resources, and providing the best answer. Therefore, resources are linked to questions rather than only provided in lists. They cover fundamental concepts, major resources in different subjects, special topics like readers advisory work and user instruction, and tools to develop and manage reference departments. This edition takes into account technological changes since the last and includes a new chapter on Reference 2.0 tools, which use new technology in innovative ways. It features free Web resources, incorporates suggestions by practitioners like the list of RUSA Outstanding Reference Sources 2005-2009, and updates resource lists.
