New Book Covers

I have noticed that several books I have purchased recently have a new kind of plastic cover/book ends. They retain the flexibility of a paperback but combine it with the durability of a hardback, without the bulk or weight. The cover is easily cleaned. I love it, especially as one of the books is a compilation of 100 Favorite Poems selected by New Zealanders that I am likely to dip into for years to come. Isn't technology great.... Grant
