The only things librarians seem to encounter more often than acronyms are strings of jargon and arcane technical phrases—and there are so many floating around that even just reading an article in a professional journal can bewilder experienced librarians, to say nothing of those new to the profession! Featuring thousands of revised and brand new entries, the fourth edition of ALA Glossary of Library and Information Science presents a thorough yet concise guide to the specific words that describe the materials, processes and systems relevant to the field of librarianship. A panel of experts from across the LIS world have thoroughly updated the glossary to include the latest technology- and internet-related terms, covering metadata, licensing, electronic resources, instruction, assessment, readers' advisory, and electronic workflow. This book will become an essential part of every library’s and librarian’s reference collection and will also be a blessing for LIS students and recent graduates.
