Here is a collection of links to useful sites related to the ancient Celts. As always, there is more to come, this site is still very much a work in progress.

Useful for researching the Greek and Roman sources on the Celts - for instance, searching De Bello Gallico for references to a specific term or name. Unfortunately, not all important works are there, and some are only included in part but not in whole.
