Automation is the use of machines, control systems, and information technologies to optimize productivity and minimize human intervention. Library automation applies these principles to libraries by using technology to automate processes like collection, processing, storage, and retrieval of information. This frees up librarians and staff to focus on more meaningful tasks. The need for library automation stems from issues like information explosion, the rise of different formats and user needs, and limitations of libraries in terms of time, space, and human resources.
