If you spy a copy by this publisher at your library, pick it up and see what you think. Click on the links under the books to grab more information - these are just a few examples. You can see the entire collection at http://www.greatillustratedclassics.com/. Oh - and it looks like you can read the first chapter of most, if not all, of the books as a .pdf by clicking on the link next to each book on their site. The books on this site are running around $7-$8 each, can also be found used on Amazon or you've got a good chance of finding them at the library.
This will be used as part of our upcoming unit study on whales and dolphins.
