Reddit mentions of The Kodansha Kanji Dictionary

I admit I use jisho.org far too often when I should be using a J-J dictionary, although I find it to strike a nice balance between ease of use and comprehension, although I admit due to its all-inclusive nature it can be misleading to people who don't already have a decent grasp of the language.

As for paper dictionaries, I'm a huge fan of The Kodansha Kanji Dictionary. I received a copy as a gift a couple years ago and it's been my go-to reference for looking up words when I'm reading offline. Even though it's technically a kanji dictionary, as an intermediate learner I find it to contain the vast majority of words I need to look up presented in a readable and useful manner, with pointers to related words and kanji for context.

A Dictionary of [Basic|Intermediate|Advanced] Japanese Grammar is very insightful, but the layout is poor. I found myself learning more trying to read it as a book (despite it being very dry) rather than referencing it like a dictionary. The quality of the content is high, though.

Thanks for the detailed post. I think the textbook-search site'll be especially handy, since I've never heard of it before.

And since you seem to know of a lot of good resources, I have a few questions (if you don't mind).

1. Would you happen to know the difference between these two Kodansha kanji dictionaries?
   
   

• Kodansha Kanji Learner's Dictionary
  
• Kodansha Kanji Dictionary
  
  I'm really not sure what to go for. I'm currently using the Kodansha Kanji Learner's Course, and it strongly suggests that Learner's Dictionary as a supplement. But at the same time, the regular Kanji dictionary seems to be the better deal since it has much more Kanji. Is there any point in owning both?
  
  

2. I'm interested in the All About Particles book, and other such supplementary texts, but is there a chance that the Dictionary of Japanese Grammar series might make them redundant?
   
   
3. How is Kodansha's Communicative English-Japanese Dictionary? Wouldn't it be redundant to the Furigana dictionary, which lets you do look-up in both JP-EN and EN-JP? Or is it nuanced enough to be worth it on its own?
   
   Thanks!
