Bloomsbury Recalled
by Quentin Bell
Published in 1996 (I finished it on April 15, 2007)
It's nowhere near great and very biased at times, but if you want an insight into the lives of the Bloombury group, there aren't too many sources to turn to. Thus, he offers his memories as to what the eccentric people were like. Note that he wrote the book far late into his life so I really question how much actually happened compared to what he "thought" happened, or what he just plain invented.

So many books … (you know the rest)
