Cataloguing question. We received a gift of 40 books in the Barbour Books "Heroes of the Faith" series. This isn't a numbered series, each book is by a different author, and the DDC numbers are all different.

Since our library uses DDC, the books will be filed in several different places. I'd like to consider filing them all together - any suggestions on whether that's a good idea or not? How would I go about choosing a DDC for our purposes?

Appreciate your thoughts!
