Some of these look well worth adding to the library. In particular, I'd like to check out Arman's Journey by Phillip Prowse and Solo Saxophone by Jeremy Harmer. Why we need yet another graded reader version of Call of the Wild, A Christmas Carol, and The Great Gatsby, though, I'm not sure. Oxford, Penguin, and Heinle all have versions of Call of the Wild, for example, and I'm sure there are other publishers with their own simplifications.
