Main Duties of Library Staff: Roles, Responsibilities and Importance in Modern Libraries
Libraries are no longer simply places where books are stored and borrowed. A modern library is an organized information centre that connects users with books, journals, digital resources, databases, technology, research assistance, educational materials, and reliable information.
Behind every successful library is a team of dedicated library staff. From selecting and acquiring books to cataloguing, classification, circulation, reference services, preservation, technology management, and user assistance, library staff perform many different responsibilities every day.
Understanding the main duties of library staff is important for library users, students of Library and Information Science (LIS), teachers, researchers, and anyone interested in how libraries operate.
This article explains the major duties and responsibilities of library staff and describes how their work contributes to an effective and user-friendly library.

Frequently Asked Questions
1. What Are Library Staff?
Library staff are the employees who manage the activities, resources, services, and daily operations of a library.
Depending on the size and type of library, staff may include:
Librarians
Assistant librarians
Library assistants
Library technicians
Cataloguing staff
Acquisition staff
Circulation staff
Reference librarians
Digital library staff
IT support staff
Administrative staff
Clerical staff
Library attendants
The exact duties vary according to the type and size of the library.
A small school or community library may have only one or two employees performing many different tasks. A large university or national library may have separate departments for acquisitions, cataloguing, circulation, reference, digital services, preservation, administration, and information technology.
2. Why Are Library Staff Important?
Library staff are important because library resources cannot organize, maintain, and deliver themselves.
A library may contain thousands or even millions of information resources, but users need an organized system to discover and access those resources.
Library staff help to:
Organize information resources
Assist library users
Maintain library collections
Provide reference services
Manage circulation
Develop digital services
Preserve valuable documents
Maintain library records
Support research and education
Introduce new technologies
Maintain a comfortable learning environment
The ultimate purpose of library staff is to help users find the right information at the right time in an appropriate form.
3. Main Duties of Library Staff
Although responsibilities differ between libraries, the major duties commonly include:
Collection development
Acquisition of library materials
Accessioning
Classification
Cataloguing
Physical processing
Shelving
Shelf reading
Circulation
Reference services
User registration
Information services
Digital library management

4. Collection Development
One of the important responsibilities of library staff is collection development.
Collection development means building and maintaining a library collection that meets the information needs of its users.
Staff may assess:
User needs
Curriculum requirements
Research requirements
New publications
Existing collection strengths
Collection weaknesses
Subject demand
Available budget
Physical space
Digital resource requirements
A good collection should contain useful, relevant, current, and appropriate resources.
Library staff may also identify outdated, damaged, duplicate, or rarely used materials for evaluation.
5. Book Selection and Acquisition
Library staff are often involved in selecting and acquiring new materials.
Resources may include:
Books
Journals
Newspapers
Magazines
Reports
Theses
Dissertations
Maps
Audio materials
Video materials
E-books
E-journals
Databases
Books may be selected based on recommendations from librarians, teachers, lecturers, researchers, students, or other library users.
The acquisition process may involve:
Selection → Ordering → Receiving → Checking → Recording → Processing → Shelving
Library staff must ensure that purchased materials match the library's objectives and available budget.
6. Receiving and Checking Library Materials
When new books or other materials arrive, library staff should carefully inspect them.
They may check:
Title
Author
Edition
Publisher
Publication year
ISBN
Number of copies
Physical condition
Price
Order details
Staff should compare the received materials with the purchase order or invoice.
Damaged or incorrect materials may need to be reported to the supplier.

Typical accession information may include:
Accession number
Date received
Title
Author
Edition
Publisher

Price
Source of acquisition
Remarks or notes
The accession number provides an important identity or control number for the library's physical collection.
Proper accession records help library staff track materials and maintain accurate collection information.
8. Classification of Library Materials
Classification is another major technical duty performed by library staff.
Classification organizes library materials according to their subjects.
Common classification systems include:
Dewey Decimal Classification (DDC)
Universal Decimal Classification (UDC)
Library of Congress Classification (LCC)
Colon Classification (CC)
For example, under the Dewey Decimal Classification system, different numbers represent broad subject areas.
Classification helps users locate related books together on the shelves.
9. Cataloguing
Cataloguing involves creating bibliographic records that describe library materials.
A catalogue record may contain information such as:
Author
Title
Edition
Publisher
Publication details
Physical description
ISBN
Subject headings
Classification number
Call number
Modern libraries often use integrated library systems or library management software to create and manage catalogue records.
A well-maintained catalogue allows users to search for resources by title, author, subject, keyword, ISBN, and other fields.
10. Labelling and Physical Preparation
Before books are placed on shelves, staff usually prepare them physically for library use.
This may include:
Attaching ownership stamps
Adding barcode labels
Adding RFID tags
Attaching spine labels
Adding book pockets where required
Covering books
Adding security labels
Writing or printing accession information
Proper physical processing makes resources easier to identify, manage, and protect.
11. Shelving and Shelf Arrangement
Library staff are responsible for keeping books in their correct locations.
Books may be arranged according to:

Title arrangement
Collection type
Correct shelving is essential because even if a book exists in the library, users may not be able to find it if it is placed incorrectly.
12. Shelf Reading
Shelf reading is the process of checking books on library shelves to ensure that they are correctly arranged.
Staff look for:
Misplaced books
Incorrect sequence
Missing books
Damaged materials
