Add URLs for Books

Many books have their page on the publisher’s website. Those pages could be used as a source to fill in data and a hint about the current publication status if the URL comes to be missing.

Solution

Allow each Work and Edition to list related URLs.

• Works could have URLs to Wikidata. Maybe an automatic discovery is possible based on ISBN.
• Editions could lead to their respective publishers based on language or other differences.

Alternatives

The minimum could be a simple array of URLs sorted manually.

Examples

I think MusicBrainz has a good system where you can define the type of URL (official, Wikipedia, Wikidata…).
