Given an ISBN, it's possible to get a large amount of information from two sources:

1. Content Cafe: Title, cover image, description, popularity measurement
2. OCLC Classify: Author information (sort name, roles, birth/death date, LC ID, VIAF ID), popularity measurements, subject classifications

Unfortunately, in neither case can we get the author's display name, which is kind of the holy grail here. Patrons generally expect to see authors' display names and we don't like to guess at them because they're very complicated.

Given a VIAF ID, it's possible to do a lookup with the VIAF API and, in most cases, get the author's display name. (Library of Congress doesn't have this information, but it is possible to look up a person through the [LC API](http://id.loc.gov/authorities/names/n78086409.skos.json) or an [LC bulk download](http://id.loc.gov/authorities/names.html) by their LC ID, in case there's any information there.)

This requires a lot of work in a lot of different places, so I'm creating an epic for it.
