Which of the following is a primary goal of a school library?

A primary goal of a school library is to provide a wide variety of resources. This objective aligns with the library's mission to support students' learning and development across different subjects and interests. By offering diverse resources, such as books, digital media, databases, and other learning materials, school libraries can cater to various learning styles and promote information literacy among students. This ensures that all students have access to the materials they need to engage in effective research and critical thinking.

In addition, a broad range of resources helps to foster a love for reading and learning, encouraging students to explore different genres and topics. Providing a comprehensive collection enables the library to serve as a vital educational hub within the school, where students can gain knowledge, cultivate skills, and fulfill curricular requirements.

The other options, while related to library functions, do not encapsulate the primary goal as effectively. For example, serving as a study hall is more of a supplementary function rather than a core goal. Reducing the number of books in circulation is counterproductive to a library's purpose, and holding annual book fairs is an event that, while beneficial, does not represent the overarching mission of the library itself.
