This is a dictionary of the Celtic place-names which appear on the maps of The Barrington Atlas of the Greek and Roman World (ed. R. J. A. Talbert, Princeton, NJ, 2000). There are alphabetically arranged files of place-names and of place-name elements. The dictionary itself is only available as a book, except for the searchable pdf map (made by Dr Keith Briggs) which is available on this site.
