Why, thank you for all the nice comments!
I do have a few of the feline mystery genre: parts of Lilian Jackson Braun's
The Cat Who... series. Very fun to my mind. I also want a few more Star Wars novels, I really enjoy them. Moreover my more recent purchases do tend towards sci-fi, for some reason military sci-fi more than space operas. Go figure.
As for
Dune, I don't have a set, but my father has the 'Frank Herbert originals' on
his shelves. And while it seems like a lot of Clancy, most of that is one series, most of which isn't written by the original authors anymore.
There's a few non-fiction lurking as well;
A Brief History of Time,
The Fabric of the Cosmos,
Infinite Ascent.
Anyway, enough about mine; show me yours!

Organisation is not a requirement!
