Discuss a purpose a call number in library?

A call number in a library serves the purpose of organizing and categorizing library materials in a systematic way. It helps library users locate specific items within the library's collection by providing a unique identifier for each item. Call numbers are typically based on a classification system, such as the Dewey Decimal Classification or Library of Congress Classification, which groups similar materials together based on subject matter.

By assigning call numbers to library materials, librarians can ensure that items are shelved in a consistent and logical order, making it easier for users to find what they are looking for. Call numbers also help library staff keep track of items in the collection and manage inventory effectively.

Overall, the purpose of a call number in a library is to facilitate access to information and resources, streamline the organization of materials, and enhance the overall user experience for patrons.
