Scholastic's Ready-To-Go Classroom Libraries are comprised of three 100-book collections per grade level. Each collection focuses on a different area of emphasis:

Favorites Collection
These collections are designed to motivate and engage reluctant readers with classic and contemporary novels that epitomize good writing. The titles will serve as the basis for author studies, literature groups and text studies.

Independent Reading Collection
Students at every reading level will find books in these collections that they can read with interest, accuracy and success. The titles are organized by guided reading level for grades K–2, and Lexile Levels for grades 3–8.

Nonfiction
Students who read widely in various content areas develop stronger vocabulary, better comprehension and greater fluency. These collections provide valuable support to science and social studies curricula. In addition, they provide students with an excellent source of information for research projects.

All titles have been selected by renowned education professionals and together constitute an effective 300-book classroom library that offers a wide range of genres, topics, authors and subjects.

Buy these collections individually, or a complete set.
These collections offer a diversity of reading levels and have a multicultural emphasis.
What's more, you may purchase each collection individually until you have purchased the entire Ready-To-Go Library. That's a considerable advantage for budget-conscious educators.
