If you think of a classroom library as a cozy, welcoming space where students can read quietly or browse through a rich collection of texts, you are only partially correct. The fact that classroom libraries are places for storage and quiet is only one small part of their purpose. They are, in the broadest sense, the backbone of classroom activity: Much of what goes on each day draws from or occurs in or around the resources and space within the classroom library.
As we see it, there are at least five important functions of an effectively designed classroom library.

1. Supporting Literacy Instruction
The first function of a classroom library is to support reading and writing instruction—in school and out. To this end, outfit your classroom library with books and other media materials to support student learning in all of the daily curriculum subjects. Include materials related to science, health, mathematics, history, economics, geography, music, art, drama, dance, languages, grammar, spelling, literature, computers, and other topics. Build an adequate collection of fiction and nonfiction materials at enough different levels to accommodate the many interests and abilities of students designing to check out books for take-home reading.

2. Helping Students Learn About Books
Next, an effective classroom library provides a place for teachers to teach and children to learn about books and book selection. Here children can experience a variety of book genres and other reading materials in a smaller and more controlled environment than in the school or public library. You can also use the classroom library to teach students how to take care of books. You can set up a book repair area for instruction on repair, and display a poster with clear directions on how to mend torn pages, remove marks in the books, cover frayed edges, or fix broken bindings.
You can also use the classroom library to teach students effective strategies for selecting relevant, interesting, and appropriate reading materials.
A good classroom library helps students locate books easily and gives them room to get comfortable.

3. Providing a Central Location for Classroom Resources
You can also use your classroom library as an organized central storage location for classroom instructional resources. Here is additional space for organizing science equipment, CD and tape players, VHS and DVD tapes, computers wired to the Internet, games, magazines, and other materials that support learning. In this respect, the classroom library mirrors the organization of media centers at the individual and district levels.

4. Providing Opportunities for Independent Reading and Curricular Extensions
The fourth important function of a classroom library is as a resource and location for independent reading, personal exploration, project research, and individual assessment. Every good comprehensive reading program provides students daily time to read independently. The classroom library is typically the resource that supports children's daily independent reading of self-selected books that meet their personal, recreational reading interests. The classroom library also provides students with readily accessible print materials, expository books, computer technology, and media for conducting research or completing curricular extension projects.
Further, an in-class library offers a setting for students to quietly read aloud and discuss a book with a peer or the teacher. This provides an ideal opportunity for you to conduct an informal assessment of each student's reading, which will help you to plan individualized instruction.

5. Serving as a Place for Students to Talk About and Interact With Books
The effective classroom library also functions as a gathering spot where students and teachers can express their lives as readers. Think of it as a place that makes books exciting, that sells reading. It should be a place students can't wait to get to. Here they can talk about their reactions to books, write a critical review and share it with peers, or draw a poster to advertise a favorite book. A few other ideas follow:

• The library can be a place where students can contribute to a list of "The Top Ten Books This Week in [__] Grade."
• It may also be a place where students can advertise a "book swap" with other students.
