Bug 14911 fixes this for the result list of the item search. It would be grat if the CSV export file could also include the additional information. It's not as simple as using the biblio-title include there too, as that adds spans that you don't want in the CSV file.
This is still something that would be nice to have in the CSV export since you can see that information in the item search results, so you would expect to see the exact same information in the export.
