Different Types of Libraries

Libraries have been around for thousands of years and today, they are still an essential part of our society. However, not all libraries are created equal. There are different types of libraries that serve different purposes and audiences. Let’s take a closer look at some of them.

Public Libraries

Public libraries are the most common type of library and are funded by the government. They are open to everyone and offer a wide range of resources including books, audiobooks, DVDs, e-books, and even computers. They also offer various programs and events such as book clubs, storytime for children, and workshops for adults. According to the Institute of Museum and Library Services, there were 9,057 public libraries in the United States in 2017.

Academic Libraries

Academic libraries are located on college and university campuses and serve the students, faculty, and staff. They offer resources such as textbooks, research articles, and other academic materials. Some academic libraries also have special collections that are unique to their institution. According to the National Center for Education Statistics, there were 3,715 academic libraries in the United States in 2018.

Special Libraries

Special libraries are designed to serve specific groups of people or businesses. They can be found in corporations, law firms, hospitals, museums, and government agencies. These libraries offer resources that are relevant to their specific field or industry and may also provide research services. According to the Special Libraries Association, there are over 9,000 special libraries in the world.

While the number of books required to be considered a library may vary depending on the type of library, what is important is that libraries continue to provide access to information and resources for all. Whether it’s a public library, academic library, or special library, they all play a crucial role in promoting literacy, education, and lifelong learning.

Factors that Determine the Size of a Library

When it comes to determining the size of a library, there are several factors that come into play. These factors include:

  • Purpose of the Library: The purpose of the library will determine the number of books it needs to accommodate. For example, a public library will have a larger collection than a school library because it serves a larger audience.
  • Target Audience: The target audience of the library will also determine the number of books required. A library that caters to children will have a different collection than one that caters to adults.
  • Budget and Resources: Budget and resources are crucial factors when it comes to determining the size of a library. A library with a limited budget will have a smaller collection than one with a larger budget.
  • Available Space: Finally, the available space also plays a role in determining the size of a library. A library with limited space will have to limit its collection size.

It is worth noting that the size of a library is not always determined by the number of books it contains. In addition to books, libraries can also have other resources such as audio and video materials, computer stations, and study areas. Libraries can also offer a range of services such as educational programs, workshops, and community events.

Library Type Collection Size Other Resources
Public Library 100,000+ Audio and video materials, computer stations, educational programs, workshops, and community events.
School Library 5,000 – 20,000 Study areas, computer stations, and educational programs.
Special Library Varies Specialized resources and collections based on the library’s purpose.

Tips for Managing a Library Collection

A library is not just a place that houses books, but it is also a place that provides access to knowledge and information. To ensure that your library collection is always relevant and useful, there are certain tips that you can follow:

  • Establish a Collection Development Policy: A collection development policy outlines the criteria for selecting materials to be added to the library collection. This policy should be based on the library’s mission, the needs of the community, and the available resources. It is important to review and revise this policy regularly to ensure that it is meeting the needs of the library and the community it serves.
  • Keep Track of Your Collection: It is essential to maintain an accurate inventory of the library’s collection. This can be done through a computerized cataloging system or a manual card catalog. Keeping track of the collection can help identify missing items, items that need to be replaced, and items that are no longer relevant.
  • Weeding Out Unwanted Materials: It is important to regularly review the collection and remove materials that are outdated, damaged, or no longer relevant. This is known as weeding out unwanted materials. This process can free up space for new materials and ensure that the collection remains relevant and useful.
  • Regular Maintenance and Preservation: Regular maintenance and preservation of the collection can help extend the life of the materials. This includes repairing damaged items, storing materials properly, and protecting materials from environmental factors such as light and humidity.

By following these tips, you can ensure that your library collection remains relevant and useful to the community it serves.


In conclusion, the size of a library and the number of books it should have depend on various factors, such as the purpose of the library, the target audience, and the available resources. There is no set number of books to be considered a library; it is more about the quality and relevance of the materials to the users.

Whether you’re starting a library or managing an existing one, it’s crucial to have a well-planned collection development policy, keep track of your materials, and regularly maintain and preserve your collection. With these tips, you can build and maintain a successful library that meets the needs of your users and enhances their learning and enjoyment.
