In reply to Stephen Edwards.
I think the only need for these materials on the Kindle might arise due to practitioners having Kindles but not tablet computers for whatever reason. I have a Partner who expressed a wish for the Yellow books on Kindle but my feeling is that it's not the right platform for this kind of extensive data. I may be biased by lacking a Kindle and owning an iPad here, my experience with Kindles being limited to attempting to migrate a Yellow book onto a Kindle (which I had permission of the publishers to do, I hasten to add).
