C.Lib, or Certificate in Library and Information Science, is a short-term certification program that provides basic knowledge and skills required to work in libraries and information centers. This course is ideal for students who have completed at least their 10th or 12th grade and wish to start a career in library services without immediately committing to a longer degree like B.Lib or M.Lib. The typical duration of the C.Lib course ranges from 6 months to 1 year, depending on the institution.
