Discuss the purpose of a call number in library?

A call number is a unique identifier assigned to each item in a library's collection. It serves the purpose of organizing and categorizing materials so that they can be easily located by library users. Call numbers are typically based on a classification system, such as the Dewey Decimal Classification or Library of Congress Classification, which groups similar items together based on subject matter.

The primary purpose of a call number is to help library users find specific items within the library's collection. By assigning a unique call number to each item, librarians can shelve materials in a consistent and logical order, making it easier for patrons to locate the items they are looking for. Call numbers also help library staff keep track of materials and ensure that they are returned to the correct location on the shelves.

In addition to aiding in the organization and retrieval of materials, call numbers can also provide valuable information about the content of a particular item. By looking at the call number, library users can get a sense of the subject matter and scope of a book or other resource, which can help them determine if it is relevant to their research or interests.

Overall, the purpose of a call number in a library is to facilitate access to information and resources, making it easier for patrons to find and use the materials they need.
