Edit I’m too much of a language nerd to not go ahead and get all three books, finally. Got it from Amazon.ca (via a third-party seller but fulfilled by Amazon) for $150 CDN, with free shipping and tax included. All books are new copies and they’re apparently in amazon’s Canadian warehouse since the delivery ETA is within 2 days. I’m keeping this topic open for anyone else who may have that question. End of edit
I intend on getting myself a copy of A Dictionary of Japanese Basic Grammar, but chances are the edition I may get is an older version. However, before I spend any money on a copy of the book, is there any major difference between editions, any reason to stick strictly to the latest revision, or are they simply reprints?
Also, I know that the Tofugo article on the subject indicated that most people will be content with only the Basic book, but should I also get the Intermediary and Advanced grammars as well? My goal is to improve my Japanese knowledge as a self-learner, not necessarily to pass any JLPT test (especially since said tests would require me to travel to Toronto or Boston).
