This work provides basic instruction in descriptive cataloguing and the MARC bibliographic format in a library or other information agency, whether at a professional or a paraprofessional level. It should be equally suitable for use by library students in universities and colleges, and others who are studying classification by themselves, either with a specific goal or as part of their continuing professional development. Since the bibliographic record is the foundation of all the tools used in a library, from catalogue to bibliography to online database, it is important for all library staff to be familiar with at least the basics. A hands-on guide, the book contains exercises to practise new skills and quizzes to test understanding. There are answers for self-checking at the back of the book.
