What’s Your Book Shelfie Style?
Not pictured: BOXES
Alphabetical (with some stacked here and there but that’s still a subset of alphabetical for me). I admittedly don’t understand the others, except perhaps personal significance, or height if your bookspace is limited in that way. But hey, everyone’s bookshelves are as they want them and that’s just fine. :D
ETA: I should say I do have some categorical divides too— like books based in a certain setting (Star Wars, Warcraft, etc) are together rather than by author. And my craft books are all together, as are ‘comic’ books (like the Hark! A Vagrant book).
I do categories and “where stuff fits.” I’m pretty good at book Tetris.
