Thank you very much for your fast response!
Ok, that is now changed, but everything else in my program is expecting
Catalogue without IO. Is there a way to change IO Catalogue into Catalogue?
Yes, but you do not want that. You will go on writing functions which
consume Catalogue and finally you will apply a Catalogue function in the
IO monad which does all the work at once.
