Talk:Collins-Robert French Dictionary

Clarification needed
"The Collins-Robert French Dictionary (marketed as Le Robert et Collins Dictionnaire Français-Anglais in France) is a bilingual dictionary of English and French derived from the Collins Word Web, an analytical linguistics database." --- The dictionary was first published in 1978. When was the analytical linguistics database introduced? Certainly not in the 70s. I've no doubt the book has been greatly revised since '78, but we need clarification on whether it is a complete rewrite. If not, it clearly doesn't "derive" from Collins Word Web.
