Thank you, Nick, for this great idea!
Works perfectly on my PRS-505. First I was afraid that my device might hang-up while loading, as the file is really big, but didn't. It works perfectly and quite fast. Why don't publishing companies make dictionarys like that in various languages (would love to have a German-English, English-German dictionary on my reader) as epubs?
Greetings and a big thank you,
Momo
