Good Morning, Conch-L, There are two used shell books available, and I need to augment my library. These are older books, and I don't know their relevency to today's identification. They are Myra Keen (opening price $9.95) and the Kira and Habe two volume set of Shells of the Western Pacific (current price $40.00). Can someone comment on whether these books would be a good addition to a too small library of shell books and if the prices are reasonable? Thanks very much, Linda
