While trying to rescue this book En Bons Termes: Introduction Au Francais Dans Le Contexte Nord-Americain
I found several editions with different spelling for the author:
Michel Alfred Parmentier
Michel Parmentier
Michel A. Parmentier

And Worldcat shows both A. and Alfred spelling for the same books. So I would have kept the longest spelling, but I'm not certain it's the right thing to do.
What do you think about that?

Which does LoC use? Which is the one on the covers of the books?

Michel Parmentier and Michel Alfred Parmentier are both spelling on LoC, and all the spelling are on the covers

Checking around the net, it appears he uses Michel A. Parmentier when publishing his own books and Michel Parmentier when translating and the dictionaries. But as I don't speak/read french I could be wrong.

I haven't seen any covers using his full name.

I don't find the cover I've seen with his full name, I must have made it up.

From what I can see, he uses just Michel Parmentier for dictionaries too. I'll do the changes accordingly.
Thank you
