Not a big enough problem to worry Auntie Alex with, so will deal with this reader enquiry myself:
Some good-looking internet resources on said topic, have no more than skimmed them myself but the sites they are on are well respected.

The last one is the Amazon page of a classic book by a great author with a great name- Zoltan.
I’ve read several books/articles by Dorynei and highly recommend his work.
Me too- he’s not just a pretty name!
The person who made the original request has just sent me a very nice e-mail of thanks. If anyone else has any requests please leave a comment after any of the posts and I’ll see what I can do
