Books

Database

This site presents the early stages of a database modelling book editions, cover art, impressions, and publication history. It renders the bibliographical data being prepared as part of the Tolkien Linked Open Data Project.

The underlying machine-actionable data will be made available on GitHub shortly.

At present, only UK publications are included.

The site is very much in-progress and subject to change. Feedback welcome.
