Adding Series Info to the Catalog

One of the flaws in our catalog is the lack of series info. Often, our catalog records will include series info for a particular book but it won't list the other books in the series. For example, our entry for Stephenie Meyer's Twilight book does list both the series and the series number for the book. However, it doesn't provide a convenient way to know the order of the other books in the series.

I'm currently exploring catalog enhancements that would allow us to show series info in the actual record. However, some vendors have a better coverage of series than others. I need your help in coming up with a list of popular books in a series that I can use to test and make sure any vendor we consider has enough information to be useful. I'm looking for examples for children, young adult, and adult series. Please post a comment or send me an email if you have suggestions I should add to my test list.
