Information & Information Architecture
A history of content and sources
Good annotation
Information displays should be annotated, combining words, images, graphics, whatever it takes to describe and explain something. Annotation calls out and explains information and, at the same time, explains to viewers how to read data displays. Good annotation is like a knowledgeable expert/teacher at the viewer's side pointing and saying, "Now see how this works with that, how this might explain that..."
An immense wordy diagram
In ~1560 Ettore Ausonia, a polymath with interests from mathematics to mirror-making, constructed an immense wordy diagram depicting reflections from concave spherical mirrors. Then, between 1592 and 1601, while teaching at the University of Padua, Galileo made this handwritten copy of the diagram, which was fortunate since Ausonio's original has since gone missing. Three helpful architectures for the off-the-grid sentences are deployed – word trees, stacklists, annotated linking lines.
No wonder you think it's complicated
We were very proud of our user interface and the fact that we had a way to browse 16,000 (!!) pages of documentation on a CD-ROM. But browsing the hierarchy felt a little complicated to us.
So we asked Tufte to come in and have a look, and were hoping perhaps for a pat on the head or some free advice. He played with our AnswerBook for 90 seconds, turned around, pronounced his review:
"Dr. Spock's Baby and Child Care is a best-selling owner's manual for the most complicated 'product' imaginable – and it has only 2 levels of headings. You have 8 levels of hierarchy and I haven't stopped counting yet. No wonder you think it's complicated."
Infinite varieties of contexts
Over the course of 10 years of using Are.na, I have fully adopted the view that any piece of information can be important to a person given the right context. And on Are.na, pieces of information can be arranged in infinite varieties of contexts – their respective meaning shifts as the proximate information shifts. In other words, the more connections a block has, the more opportunities it has to be a nodal point.
Nodal points
I started thinking about all the other important “nodal points” (I don’t know what else to call this) of people, places, books, albums, websites, etc. that all played a part in shaping who I am as a person and what I think is important. These points are a combination of seeking things out myself and getting a recommendation that felt like it was actually for me. A mixture of both passive and active knowledge acquisition.
ultimately, it's the totality of those “nodal points” that indicate one’s own unique perspective. It doesn’t matter if you specifically sought out the nodal point or not, it’s the recognition that counts. When you encounter a piece of life-changing information (no matter how large the change part is), you are simultaneously discovering and creating “yourself,” becoming incrementally more complete. Your perspective (where your gaze is directed) is made up of a meandering line through these points. Learning (or maybe some precursor to learning) is a lot about developing the intuition to recognize when something you find in the world is going to be a nodal point for you.
What is a commonplace?
In all cases, a commonplace is a method of compiling knowledge for later use. In digital or analog form, this continued growth of stored ideas and projects is a key driver of intellectual development. Any time you decide to work on a project, you should attempt to collect and categorise all information that is relevant and useful.
Reveling in infrastructure

When the Smithsons placed the water heater for the Hunstanton Secondary School prominently above the school’s roofline, they weren’t just revealing the building’s infrastructure, they were reveling in it. What does it look like to do this on the web?
Of course there’s no single answer, because the web is simultaneously a physical and digital medium. It is material and it isn’t. It depends on how literally you interpret the question. But taking it somewhere in-between, seeing the web as primarily an information medium, we can ask the question a little differently: what does it look like to design something that is true to the material of digital information?
The quality of thought
It is the quality of thought and the information we use that determines yield, not the size or quality of the site.
A dot went for a walk
A dot went for a walk and turned into a line.
The dot, the line, the dance, the story, and the painting had found connections. Memory became learning, learning became understanding.Learning is remembering what one is interested in. Learning, interest, and memory are the tango of understanding.
Creating a map of meaning between data and understanding is the transformation of big data into big understanding.
The dot had embraced understanding.
Understanding precedes action.
Each of us is a dot on a journey.The need to record
With collecting comes the need to record. A specimen without a label is simply a (sometimes) pretty object. Without its associated data it is scientifically worthless.
The lapse of many years
At this point I wish to emphasize what I believe will ultimately prove to be the greatest purpose of our museum. This value will not, however, be realized until the lapse of many years, possibly a century, assuming that our material is safely preserved. And this is that the student of the future will have access to the original record of faunal conditions in California and the west, wherever we now work. He will know the proportional constituency of our faunae by species, the relative numbers of each species and the extent of the ranges of species as they exist today.
— Joseph Grinnell, 1910
Information imposters
Information imposters: This is nonsense that masquerades as information because it is postured in the form of information. We automatically give a certain weight to data based on the form in which it is delivered to us. Because we don’t take the time to question this, we assume that we have received some information.
My favorite example of this is in cookbook recipes that call for you to “cook until done.” This doesn’t tell you very much. Why bother? Information imposters are fodder for administravitis.
Like a prism
When you look at phonemes, you look through the perspective of morphemes, which are one linguistic level higher. The higher level is like a prism that splits the light in two. What was one thing, like ‘length’ at the phoneme level, looks like two opposite things ‘long’ and ‘short’ from the perspective of the morphemes. In practice, when you find both a word and its opposite, then the phoneme is not about either of these two things, but about what is common to them.
Thinking in terms of outputs
In our use of digital and analogue filing tools, we classify information through folders. An article about railway construction gets filed under ‘infrastructure’ or ‘transport’. In Evernote we tag it with ‘rail’ or ‘construction’. This is thinking like a librarian and not like a writer. We are classifying the information as an input. The reason you take notes as a writer is to produce content. It makes sense, then, to take notes in line with this goal.
Traditional filing like this tends to fail when you attempt to write your content. You are stuck trying to figure out which categories will be relevant for your proposal, paper or blog post. Interesting writing often comes from connecting separate fields through a common idea. By revealing the common denominator. By unifying two seemingly-contradictory ideas. How can you possibly achieve this if you’re looking in the same category for your information? The categories simply do not fulfil the function required by the writer.
The notes you take and indeed, the way you process information, should be with a specific project or idea in mind. You must classify information in terms of its outputs. When you take notes on a book, think about how this could apply to a specific idea you had or how it argues against a paper you read last week. The premise is that you should be organising by context and always trying to connect the dots between the content you're consuming.
Off to the races
"You get to the point where you're about to place your wager; the race is about to be run. You evaluate the sum total of the information, which has to do with how the money has been bet, what the horses looked like on the track, all this information—and it's like you run your hand over the race—I've had this happen so many times, it's the only way to explain it—you run your hand over the race. All the information is logically there, but there's something wrong. You don't know why something is wrong, but something is not correct. Then I have to reevaluate everything in terms of this feeling I have about the thing, which is derived from information, but which is so complex and so intricate and so subtle that there's no way you can put a tag on it."
The pie has been made
"In today's world, boundaries are fixed, and most significant facts have been generated. Gentleman, the heroic frontier now lies in the ordering and deployment of those facts. Classification, organization, presentation. To put it another way, the pie has been made—the contest is now in the slicing."
The Visual Information Seeking Mantra
There are many visual design guidelines but the basic principle might be summarized as the Visual Information Seeking Mantra:
Overview first, zoom and filter, then details-on-demand
Overview first, zoom and filter, then details-on-demand

It proved to be only a starting point in trying to characterize the multiple information visualization innovations occurring at university, government, and industry research labs.

The medium is the message
A Quote by Marshall McLuhanProduct Design Resources
A Reference Work by Brandon DornThings I‘ve read, people I‘ve tried to learn from, and things I‘ve done to become a better designer. This is an idiosyncratic list reflecting what has helped me along the way, rather than an exhaustive list of design classics.
Though the list leans toward theory — principles are more durable than technique — I offer a few ideas further down about how to practice design. It also leans toward information design, because the task of presenting rich, dense information in an accessible way is ultimately the task of any digital product.
Blogging with Version Control
An Article by Will DarwinI’ve been musing for a while now on the way blog posts are typically presented—in reverse chronological order. This format has never truly made sense and does not reflect the way good writing and thinking happens.
...The main issue with the ‘pile’ system is that this post is eventually buried beneath more recent pieces of writing; there is no incentive for revisiting or updating the work. Even worse, if an author does decide to unearth the piece and make some major changes, those who read the original piece are not made aware of these alterations. The sorting order is static.
Nobody gives a hoot about groupthink
An Article by Baldur BjarnasonTwo relatively common ‘fashions’ today are real-time collaboration and shared data repositories of one kind or another.
Both increase productivity in the naive sense. We work more; everybody is more active; the group feels more cohesive.
The downside is that they also both tend to reduce the quality of the work and increase busywork.
Two types of work
An Article by Jorge ArangoThere are two types of work: growth work and maintenance work.
Growth work involves making new things. It can be something big or small. In either case, growth work often follows a loose process.
Maintenance work is different. Maintenance work involves caring for the resources and instruments that make growth work possible. This includes tools, but also body and mind.
Maintenance is ultimately in service to growth. But effective growth can’t happen without maintenance. As with so many things, the ideal is a healthy balance — and it doesn’t come without struggle.

A City Is Not a Tree
- Strands of life
- Impending destruction
- The right overlap
- The difficulty of designing complexity
- Political chains of influence
Strands of life
For the human mind, the tree is the easiest vehicle for complex thoughts. But the city is not, cannot, and must not be a tree. The city is a receptacle for life. If the receptacle severs the overlap of the strands of life within it, because it is a tree, it will be like a bowl full of razor blades on edge, ready to cut up whatever is entrusted to it. In such a receptacle life will be cut to pieces. If we make cities which are trees, they will cut our life within to pieces.
Impending destruction
In any organized object, extreme compartmentalization and the dissociation of internal elements are the first signs of coming destruction.
The right overlap
Overlap alone does not give structure. It can also give chaos. A garbage can is full of overlap. To have structure, you must have the right overlap.
The difficulty of designing complexity
Designers, limited as they must be by the capacity of the mind to form intuitively accessible structures, cannot achieve the complexity of the semilattice in a single mental act. The mind has an overwhelming predisposition to see trees wherever it looks and cannot escape the tree conception.
Experiments suggest strongly that people have an underlying tendency, when faced by a complex organization, to reorganize it mentally in terms of non-overlapping units. The complexity of the semilattice is replaced by the simpler and more easily grasped tree form.
Political chains of influence
In Chicago, formal chains of influence and authority are entirely overshadowed by the ad hoc lines of control which arise naturally as each new city problem presents itself. These ad hoc lines depend on who is interested in the matter, who has what at stake, who has what favors to trade to whom.
This structure, which is informal, working within the framework of the first, is what really controls public action. It varies from week to week, even from hour to hour, as one problem replaces another. Nobody’s sphere of influence is entirely under the control of any one superior; each person is under different influences as the problems change. Although the organization chart in the Mayor’s office is a tree, the actual control and exercise of authority is semilattice-like.
Same name in the same basket
Does a concert hall ask to be next to an opera house? Can the two feed on one another? Will anybody ever visit them both, gluttonously, in a single evening, or even buy tickets from one after going to a performance in the other?
In Vienna, London, Paris, each of the performing arts has found its own place, because all are not mixed randomly. The only reason that these functions have all been brought together in Lincoln Center is that the concept of performing art links them to one another. The organization is born of the mania every simple-minded person has for putting things with the same name into the same basket.
Separation of concerns
Another favorite concept of the CIAM theorists and others is the separation of recreation from everything else. This has crystallized in our real cities in the form of playgrounds. The playground, asphalted and fenced in, is nothing but a pictorial acknowledgment of the fact that ‘play’ exists as an isolated concept in our minds. It has nothing to do with the life of play itself. Few self-respecting children will even play in a playground.
Play itself, the play that children practice, goes on somewhere different every day. In a natural city this is what happens.
Structural complexity
The idea of overlap, ambiguity, multiplicity of aspect, and the semilattice are not less orderly than the right tree, but more so. They represent a thicker, tougher, more subtle and more complex view of structure.
Neighborhoods
We cannot get an adequate picture of what Middlesborough is, or of what it ought to be, in terms of neighborhoods. When we describe the city in terms of neighborhoods, we implicitly assume that the smaller elements within any one of these neighborhoods belong together so tightly that they only interact with elements in other neighborhoods through the medium of the neighborhoods to which they themselves belong. Ruth Glass herself shows clearly that this is not the case.
Cities which are trees
Columbia, Maryland
Greenbelt, Maryland
Greater London Plan
Mesa City, Paolo Soleri
Tokyo Plan, Kenzo Tange
Chandigarh (Le Corbusier)
Brasilia, Lucia Costa
Communitas (Percival and Paul Goodman)
Roman town evolved from military campsIn the worst cases, the units of which these cities are composed fail to correspond to any living reality; and the real systems, whose existence actually makes the city live, have been provided with no physical receptacle.
In a tree structure, it means that within this structure no piece of any unit is ever connected to other units, except through the medium of that unit as a whole.
Sets and systems
When the elements of a set belong together because they cooperate or work together somehow, we call the set of elements a system.
From a designer’s point of view, the physically unchanging part of this system is of special interest. I define this fixed part as a unit of the city.
Whatever picture of the city someone has is defined precisely by the subsets he sees as units.
Natural and artificial cities
I want to call those cities which have arisen more or less spontaneously over many, many years natural cities. And I shall call those cities and parts of cities which have been spontaneously created by designers and planners artificial cities. Siena, Liverpool, Kyoto, and Manhattan are examples of natural cities. Levittown, Chandigarh, and the British New Towns are examples of artificial cities.
It is more and more widely recognized today that there is some essential ingredient missing from artificial cities.
Trees and semilattices
The tree of my title is not a green tree with leaves. It is the name of an abstract structure. I shall contrast it with another, more complex abstract structure called a semilattice.
Both the tree and semilattice are ways of thinking about how a large collection of many small systems goes to make up a large and complex system.
A collection of sets forms a semilattice if, and only if, when two overlapping sets belong to the collection, the set of elements common to both also belongs to the collection. That is, if [234] and [345] belong to the collection, then [34] belongs to the collection.
A collection of sets forms a tree if, and only if, for any two sets that belong to the collection either one is wholly contained in the other, or they are wholly disjoint. Every tree is trivially a simple semilattice.
We are concerned with the difference between structures in which no overlap occurs, and those structures in which overlap does occur.
The semilattice is potentially a much more complex and subtle structure than a tree. It is this lack of structural complexity, characteristic of trees, which is crippling our conceptions of the city.
