This year marks the anniversaries of some of the most beloved books for children and young adult readers. While many books' shelf-life may be short since there are so many new titles published annually, some live on to become classics with generation after generation enjoying the imagination they provide.

“Treasure Island” by Robert Louis Stevenson (published 130 years ago in 1883) and Jack London’s “Call of the Wild” (published 110 years ago in 1903) are examples of the timelessness of literature that is still accessible in book, audio and e-book form for readers.

The following titles have been in print for years and are ready to be celebrated and enjoyed again.
