Improve roll-ups logic so the unlike items do not roll up together.
We have noticed several instances where unrelated titles roll-up together. We have noticed it the most in travel books. It seems to be a problem whenever we don't use a 1XX Marc Fields in a record and several items have the same 245, or in records where the 1XX field and 245 are the same but are in fact different books. Travel books are a problem, but I've seen this in items where there is a adult and juvenile or teen version of an item, where a classic book has a graphic novelization or even in two completely unrelated items with the same time. Ideas we have had are using the audience in the 008 field in the logic, or perhaps publishers information. I am attaching some screenshots as examples:

We are consistently running into problems with picture books and easy reader editions of the same title rolling up together. Since the author and title fields are identical it will not separate them and it's very confusing to the public and staff. I have made sure to add a 250 field to show the edition, but this is only helpful if the user selects the edition information view which is an extra step.
