We've added several Christmas titles this week and I took the liberty of going through the library and tagging all of the books (except bibles) that were missing a Christmas tag. It's very possible I've missed some so please have a look and see. Also, if you post a new book, please don't forget to add the tag. I don't think we use that tool as effectively as we could.
