If you'll forgive me for paraphrasing Dewey.
It's Christmas shopping time again, and my mother visited to do her shopping this weekend just past. She wants to buy my daughter books for Xmas, so she dragged me along. Not because I know what my daughter likes to read: because I'm a bibliographer. Well, that's not the terminology that she used, but I was clearly wandering around the childrens' department of Chapters applying the usual collection development criteria to book selections for a collection serving a single 9 year old girl.
