Upset about the lake of pre-historic children's tails and books

My group for Chpt. 10 had to read children's books based on prehistory or tales from ancient eastern cultures. Granted these are not the most interesting subjects but there was a serious lack of literature based in this genre. Out of about ten books listed in the the text on the subject the Catawba County Library only has two (one being a Newberry Award winner) the other is a middle part of a series of books which they don't carry the rest. This disappoints me.
