Polo is quite interested in the five-volume Worldmark Encyclopedia of Cultures and Daily Life. I explained to him that it contains articles that its articles focus on "the traditions, living conditions, and personalities of many of the world's people groups. Further, this resource provides information in twenty different headings -- everything from language and location of origin to folklore, religion, sports, interpersonal relations, foods, and living conditions. Not that Polo pup intends to travel, but if he did, he'd certainly want to know what to expect. For example, does a particular people group eat anything really interesting? Does their style of communication involve lots of wild gestures? How many people live in one house, and do they sleep on soft beds that he could share?
Poor Polo would really like for me to bring these books home so he could learn more, but they are intended for use in the library only. He'll have to come to them, and prepare to settle in for a long session of discovery.
