David has discussed arranging books by color; something we do over here as well. He brings up getting "to know a book by its cover" but what i've realized is that you cannot count on the cover color to bleed around the corner. So you're really getting to know the book by it's spine; which, on a case by case basis, may or may not be the same as getting to know the book by its cover.
Some of you might prefer to organize by theme, but many of the titles on our shelves (and yours too I suspect) carry multiple, provisional themes -- making that difficult. Does, for example, Zsa Zsa Gábor's How to Catch a Man - How to Keep a Man - How to Get Rid of a Man go under 'self help' or 'comedy'? I could probably come to a decision today but five years from now (the next time, in all likelihood, I'll pick up this book), that choice may seem foolish. Or worse yet, the choices may be ever-equally appropriate. In this case what do you do? Buy a second copy, insert a block on your shelf directing you to the section in which it's filed? Anyone who's ever spent time at "Reel Video" in Berkeley, California can attest to the absurdity of the dual/multiple category system.
So how about those taxonomies which order things by focusing on some sliver of an object that imparts to us nothing as to the content of that object. This of course is not so different from arranging your books in alphabetical order-- a description, a flattening that technically has nothing to do with what's inside. Can we say, "this book, in addition to being about handling heterosexual romance from the woman's point of view, is about its having been written by Zsa Zsa Gábor?" (in this case I think so, Zsa Zsa is a special presense, but it is hardly always, or even often, the case). Can we add to that, "this book is also about its spine being white"? Maybe not, but if we're willing to, we've removed the need to know the author or editor (particularly difficult to remember!) of the book, and can zoom to the 'white section' where it shouldn't be difficult to locate.
I would enjoy talking more abouth this and hearing from those of you who have other alternative systems of classification.
Finally, sorting by color can really beautify your bookshelves!
