Well done! I am trying to get the books in the spare bedroom arranged in some form of order (especially important when books are double-stacked, I feel), which for the history books means in date order, but in practice that's actually incredibly difficult to do. Where, for example, would one file a book on the history of misogeny, or absinthe, or prostitution, or homosexuality, or.....? And it's not even as though I could have a shelf for these outliers - many of my history books deal with themes analysed over long periods of time. I imagine P did not have such problems with the DVDs - or did he?
