When an existing author is selected as a new author when editing a book,
if they have an ISNI ID recorded we check the record and augment the local
database record from the ISNI data.
Also dedupes author aliases for this feature and when adding a completely
new author.
If an existing author has an isni on record and it matches an author from the isni api call,
display the isni short description to aid with identifying the appropriate author.
Check the authors suggested from the local DB for a matching ISNI when pulling authors from ISNI.
i.e. we do not want to suggest the same author twice when we *know* it is the same author.
If a user selects an author pulled from the ISNI service when editing a book, use any relevant data from ISNI to populate the new author record.
This includes
- bio
- aliases
- isni
- wikipedia url
- viaf
