For the 8th edition, the well-known standard work has been completely updated, significantly expanded, and partially redesigned. All fundamental steps involved in acquisition, cataloging, collection management, and usage are described in detail, with an emphasis on new developments and technologies. In line with their importance in modern library practice, various types of electronic publications are comprehensively presented alongside books and audiovisual media. A substantial new section titled "Library Information Services" focuses not only on bibliographic information tools and specialized catalog forms but also on various information offerings for journals and databases, subject-specific information portals, digital libraries, internet research, different forms of virtual reference, and more.
