When it comes to the organization of knowledge, a lot is revealed by the system of organization that's used. For most serious academic libraries in America, the organizational system of choice was invented in 1874 by Melville Louis Kossuth Dewey (or Melvil Dui, as he liked to spell it), who was an assistant librarian at Amherst College when his eponymous system was devised.
The Dewey Decimal Classification system (or DDC) is definitely widespread, however there are some notable exceptions. The Library of Congress, for example, has its own system known as LCC. And the New York Public Library has not one, but two, arcane systems: one is the Billings Classification, a broad subject classification created in the 1890's and recently retired in favor of LCC; the other is a fixed-order scheme arranged by the size of books.
So that's how the pros do it. But what about the rest of us?
Before I consider this question, let's get back to Dewey for a second. A trailblazer in many ways, Dewey was the founder and editor of Library Journal, a cofounder of the American Library Association, and an outspoken advocate of spelling reform, a 19th-century movement which suggested changing odd-looking British words like "catalogue" to more familiar-looking American ones like "catalog."
One of the words that would have caught Dewey's eye was "colour" or, more patriotically spelled, "color" and on this subject Dewey's opinions were perhaps a bit unorthodox. Later in his life, Dewey sponsored several pamphlets about Ro, a language created by Rev. Edward Powell Foster in which words are constructed using a categorical system similar to Dewey's own system for books. In Ro, words starting with "bofo-" are color words, as in "bofoc" for red (c=crimson?), and "bofof" for yellow (f=who knows?). Doesn't exactly roll off the tongue, does it? Replace the color words of this lovely final line from Robert Haas's poem "The Problem of Describing Color,"
Red, I said. Sudden, red.
with its Ro equivalents:
Bofoc, I said. Sudden, bofoc.
The poetic effect is not really the same. It's a bit like saying the hexadecimal color equivalent of medium goldenrod "EAEAAE" out loud. Like a computer language, Ro is not a language of nuance, it is a language of hard, driving logic. Such a regimented worldview may have also shaded one of Dewey's other unorthodox color opinions: he was rumored to be an extreme racist and advocate of racial segregation.
Questionable personal beliefs aside, I have never found the Dewey Decimal Classification system to be an accurate reflection of how books are organized in my own mind or anybody else's for that matter. Certainly I understand the DDC's advantages when when it comes to large-scale collections, but if how we choose to organize our personal effects says something about who we are, then an arbitrary numeric system says very little about me. My library is, to borrow from Georges Perec, "a sum of books constituted by a non-professional reader for his own pleasure and daily use." Perec's definition comes from a wonderful essay of his titled, "Brief Notes on the Art and Manner of Arranging One's Books" [found here], and includes such other quoteables as "The problem of the library is shown to be towfold: a problem of space first of all, then a problem of order." I am well aware of both.
Perec lists several possible ordering schemes in his essay, and in practice I have used a number of these, sometimes alone and sometimes in combination with one another. Randomness (or chance) has dominated certain shelves of mine for a while. Loose categories governed by architectural constraints was a working method of mine, too, with a large wall grouping my novels and a side table sheltering the smattering of books I have on the dramatic arts. Sometimes the size of the books themselves is the governing agent: I have ganged up a set of cheap paperbacks on a squat shelf because they fit there splendidly. A book's value can govern my placement of it: for example, I keep my expensive books away from the sun. In other cases, time is the reason for a book's placement, with older books piling up a dark corner of my studio while newer books are proudly displayed on my coffee table. (Though there is some method to my madness, I still take solace in Terry Belanger's aptly-named Lunacy and the Arrangement of Books, which profiles several of my predecessors.) The central issue, as Perec warms us, is that "None of these classifications systems is satisfactory by itself," and he is right. But one idea from his list, "ordering by color," seems to be gathering a small following of late, particularly among the visually-inclined.
Recently, I stopped by a design studio in my building called Thumb to see my friend Luke Bulman. He'd just reorganized his books by color, and I asked him why he did it. A few reasons that resonated with me, and helped to illuminate his logic.

For one, books he's purchased or received as gifts are books he knows and often loves, and the color of these books is a major part of the experience of interacting with them. He's not the only one. When I glance at my own bookshelf, I immediately react to the black spine and stacked caps of Tibor, the metallic silver heft of a monograph on Frank O. Gehry, the austere white backdrop of Sol Lewitt, and the optical orange punch of the 15th edition of The Chicago Manual of Style.
Another of Luke's reasons is this: organizing his books by color allows him to discover new and unexpected relationships between books he knows well already. When two unrelated books are forced to occupy the same shelf simply because of their spine color, the shelver is asked to think about whether they have ideas to share between them. Perhaps, the designers of these chromatically-related books saw something in the books' content that even their authors did not. Maybe their ideals share a common hue?
The orange of my Chicago Manual of Style (which in my own theoretical color-coded library would be shelved next to Alberto Manguel's A History of Reading) seems to support this romantic notion about the color of ideas, which has been explored more fully by Dmitri Siegel in his short piece for Dot Dot Dot 8 entitled, "Why Are All These Books Orange?" Siegel shows four books at the start of the piece: An Introduction to the Principles of Transformational Syntax, Metacritique: The Philosophical Argument of Jürgen Habermas, Adorno and Horkheimer's irresistible "Dialectic of Enlightenment", and, last but not least, The Meaning of Contemporary Realism. None of these, despite their common sunny color, are exactly what you'd think of as beach reading. In thinking over the titular question, Siegel decides that "I search out these books because their relentless orangeness speaks to the relationship between theory and visual practice. Just as the designer enforces a uniform surface to market this genre, the content of the genre theory itself is used by savvy designers to add a marketable mystique to their work."
This "marketable mystique" may also be a part of Luke's final reason for organizing his books by color: pleasure. Our bookshelves often take up a good deal of space in the places we live and work, and organizing them by color transforms them from a banal backdrop into a poppy, rainbow-colored focal point. Books organized by color are cool to look at. Just ask designer Mark Owens, who transformed a photograph of color-coded binders in at a European office supply store into a 15-second bumper for the MTV show "Video Clash."

Or ask artist Chris Cobb, who (along with 20 volunteers) recently reshelved the 20,000 books at San Francisco's Adobe Bookshop according to the color wheel.

Even The New York Times Magazine's style section recently featured the home of art collector Andy Stillpass, which houses a number of site-specific works by leading contemporary artists in a wide variety of media, including Stillpass's own books, which were rearranged first by Dominique Gonzalez-Foerster to form "The Blue Vein" in 1993 and then further juggled by Rirkrit Tiravanija to form "The Red Threat" several years later.

The more you look, the more you see an enthusiasm for color-coding in every corner of our culture. A cursory glance at Flickr does well at articulating the range. Users there are sharing photos of color-coding systems they've observed on everything from condiments to bike racks, from dress shoes to trash cans. In addition to books, I know a number of people who've organized their records by color, and this makes lots of sense too. The many moods of music seem well-suited to color-coding, as does the indescribably abstract quality of the artform itself.
So, will Pantone's numbers replace Dewey's decimals anytime soon? Probably not. But don't let that discourage you. To rearrange your books is to see them afresh and to investigage yourself in the process. Even if you make a terrible mess, Perec reminds us that "Disorder in a library is not serious in itself; it ranks with 'Which drawer did I put my socks in?'" and your sock drawer is probably color-coded already.

I hate to nit-pick here, but the cataloging system that is most widely used by research and university libraries (e.g. 'most serious academic libraries') is, indeed, the Library of Congress system.
DDS is mostly used in public libraries, not academic libraries. In fact, the DDS is not in the public domain, and libraries that use it must pay a fee to OCLC...

Presumably the books on your shelves are all known objects to you, organizing them by color does indeed allow you to explore relationships between them that you might not otherwise have thought about.

Peter, in terms of Warhol's "spines backward" phenomenon, I'm sure it has a lot to do with decorating, and you can see an example of it from this month's Pottery Barn catalog here. It's interesting to me how the spine-edges of the books give us such great information but the trim-edges of the books give us none. How one is a way of potential organization and the other simply decoration.
Thanks to the librarians for setting the record straight on DDC vs LCC - I'm being educated all the time. Much appreciated.

Are they ROYGBIV?
Alpha by author after that? or...
Alpha by subject after color? or...
Alpha by color? or...
Color based on author? or...
Color based on subject? or...
??? ...
And what colors are included? RGB? CMYK? Pantone ( by number )? Crayola? TOYO? ( And what the heck is TOYO anyway? )
I'm going to stick to books arranged by Moran. Much better system in my view.
HA! ( hazy azure -- the new mauve )
Respectfully,

I remember seeing a piece by Rachel Whiteread consisting of a cast of a library. The coloured books (cheap paperbacks, probably) had left a faint trace on the plaster. Lovely.

I didn't set up rules about how much of a single color would qualify a book for a certain color section. What does one do when the spine is half-yellow and half-green? Hmm.
and second, a complete chromatic reordering to the collection seems a bit dogmatic. I like that there are chunks of color among the heterogeneity. In the end, the organization is inconsistent: some sections by size, by subject, by publisher too. It is a small collection so a singular organizational rigor seems, well, a bit too rigorous.

Continuing in this strain, organizing by color is not so much a classification system as it is a means of interior design. Which is not to say that this method isn't visually attractive or couldn't suffice in small collection in which locations could be easily recalled, but a more effective means of achieving this end in a large institution would be to classify books according to the LoC standards and then have different subjects rebound in the desired color(s) (which is what was done for the British libraries at the top of the page).

When I was done and lived with the new shelf a few months I realized how much more organized it looked compared to the three to its right (which remained alphabetical, by subject). Gazing at the color-coded shelf created a feeling of calm, continuity, while the other three looked disjointed, chaotic.
Now all of the shelves are arranged by color, with the pattern going across the four shelves, from top to bottom (approx 2,000 books). Yes, there is an aspect of interior design here: the books create an ambiance.
Suprisingly, I rarely cannot find a book I am looking for. Having touched each and every one of my books in a relatively short amount of time for the first time, I remember what they look like, not just how they made me feel, or what they sounded like to my imagination, or where I was when I bought or read the book. In this sense, the new arrangement adds to the richness of each book.
I have since arranged the bookshelves in the other parts of the house in the same manner. I love it.

True, and this(or Rob's pre-placement of Manguel next to the Chicago Manual) gets a bit at the denial that I see in these stunts. They're either ordered by color, or they're not; anything else suggests surreptitiously imposing a different, more recognizable order on something pretty much completely removed from the books or even yourself. (This isn't aimed at you so much as you're just the example in front of me. I don't care what you do with your books *grin*)
I'd forgotten the other day: Of interest here is also Henry Petroski's The Book on the Bookshelf. While primarily a history of shelving, there's an appendix giving a page or more each to twenty-five organizational systems he's encountered. Yes, color's included, and a really nice-sounding example at that. But two others stuck out for me: strict order of publication, or acquisition. Both, and especially the second, could provide some interesting context to any given book while remaining fairly intelligible.

I truly enjoy book stores that are organized by publisher. This is rare in the US these days. There are publishing houses, such as Kodansha Globe, or Europa, that I purchase because of the respect I have for the house, and the quality of books to date. Scanning shelves to find spine designs of the different houses is not as fun.

what i find beautiful about the adobe bookshop project is that it takes the chaos of the neighborhood bookstore and applies a very simple ordering system based on something essentially visual like color. you look at it in a different way. despite the strictness of the system, there is still a lot of personality in terms of the variation of color tones, shapes, thicknesses, and sizes.

It seems an odd contradiction to me that such a utilitarian establishment would choose, for one facet of its retail, to drag function around on a leash held by form, as it were.

In the original design, the covers were purely typographic, with the bright colors used to differentiate titles. More recent covers feature images.
I haven't yet found a good image online of the books together, although there's a small page at the Goethe institute which shows the spines:

Also, here's a page with some examples of Suhrkamp covers, new and old:

This brings to mind a story about the late Sufi writer Idries Shah. Someone visiting his house in England was found by an associate in the library, trying to make sense out of the strange assortment of books on the shelves. The associate smiled and explained: "You assumed these books could give you an indication of Shah's tastes in reading. In fact they're there to give him an indication about you. I expect your eye has run along these titles when you've been in this room with Shah. You can take it that all the titles you passed over, or paused at, were noted by him and helped in an assessment of YOU".

"The problem of the library is shown to be towfold[edit: twofold?]: a problem of space first of all, then a problem of order."
Other than that, this seems like such a designery thing to do. I could only imagine a lot of us out there creating spacial arrangements based on compliments and triads and all that.
I recently visited a clothing boutique in Atlanta (called Wish, for those in the area) that used hundreds of black books with different colors of foilstamped titles on the spines to line their shoe room in the basement. It was very interesting and now surprisingly relative (for me) to this article.

I'm amazed I've not thought of it myself. You'd know what I mean if you ever saw my garden, clothes on the washing line, wardrobe, Linen closet .... ad infinitum.
Maybe I didn't think of books because my librarian mother influenced me into more logical arrangements...?
