The expanded CILIP Framework of Qualifications, with its introduction of Certified Membership for staff in paraprofessional roles, reflects the continuing need for a textbook to replace earlier editions as the standard work for paraprofessional library and information staff and for the introductory year of professional LIS courses. Fully revised and updated, the third edition of this introductory guide to library and information work introduces support staff, paraprofessionals and LIS students to the workplace. Informing the reader of the latest developments in the field, the text provides a practical, educational underpinning to library and information work across all sectors. It introduces the structure and functions of the principal types of library and information service and looks at the key information skills and areas of competence necessary for the efficient and informed practice of a wide range of tasks. Also included are sections providing useful sources of information and a glossary of abbreviations and acronyms. This is an essential self-development tool for all new entrants to the sector. It is ideal for paraprofessional training and as a continuing professional education reader for the non-professional.
