Study materials: Japanese Graded Readers

I've been putting together vocabulary flash cards on memrise.com for JGRs. Level 1, volume 1, books 1 through 4 are up. They test pronunciation (kanji <-> kana) and meaning (kanji <-> English).

It's free, of course. I'd really appreciate it if anyone who uses it points out errors so I can correct them.

I'll be adding to them as my teacher has me move on to each new book. Of course if someone else wants to do the work to build onto the course, it would be quite welcome. I'd only ask that they follow the system already established.

Some links would be handy. There are a number of graded reader-related items in the Japanese category, but it doesn't look like any of those are yours (unless you use a different name there).

Terribly sorry.

Level 1, volume 1 is completed and up (books 1-5). Level 1, volume 2, book 1 is up.

A few words might be repeated from one level to another, but I tried to be careful to avoid that.
