I can't find those books to buy anywhere, it's not even on the list of the books that Klaipeda university publisher sells. Guess the run of all those 3 books was not so big.
I have a book published by Versme about another district where my ancestors and it's really like an encyclopedia with photos, it's even more than 1000 pages. If you ever get a chance to buy it when it will be released, I'd recommend you to check on it.
