Comment 1 for bug 294475

We could add weight to the edition record for:

1. number of fields in the record
2. number of words or bytes in the record
3. presence of table of contents field
4. presence of 'linking' fields (isbn, lccn)
5. presence of subject headings

When we have works, we could add weight for:

6. number of editions of a work
7. allow users to assign 'stars' to a work (weight for stars, and weight for number of users who have assigned stars)
8. number of reviews of the work
9. work has wikipedia entry
