but it's going to take a very long time as I don't actually know for the most part which one of us read what. It's going to take research on every book. :S
For now though, our currently-reading shelf is up to date, with all of them tagged with the various alters reading them. :) (you'll notice is quite rare for only one of us to be reading a book at the same time - we view reading as a group activity as others will listen to whoever's reading, so we have to make sure we have the right book for the right group of people we have out else it won't work very well)
And off to do other things for now. If I don't manage to finish this ginormous undertaking at some point in the future it's okay, at least things will from now on be shelved correctly as people are reading them and it will eventually be mostly sorted out.
