Here Im going to try to keep track of errors in the naming of magic cards in non-english printings, starting with European languages.
I have made a program that from a .csv input compile a list of non-matching posts. It is available here but to get any use of it accurate card list is needed, see below.

Here are the output I have gotten so far: German, French, Italian, Portugese, Spanish
The main problem have been data collection, this have resulted in a so-so database.
I have managed to fix most of the errors in the English card names, the foreign I have little chance with unfortunately.

If you are a player from one of these countries or a collector and would like to help, please follow a few simple steps:
(Many may be small errors like ´ instead of ', lower case instead of upper, accents and so on, but they are equally important!)

- Save the text file to your computer
- Compare each card name to an actual card, please.
  - If a line in my file is correct -> delete it.
  - If you dont know -> just leave it.
  - If it was wrong and you corrected it -> TAB it in one step.
- Save the file and mail it to me: agzz-at-team286-dot-org.

Also if you have good lists of any of the Beginner-sets or Portugese and Spanish 9th edition, pleases let me know as well.
When I have a database I feel is accurate enought it too will be available here, of course.
