Good web site consultants know that you can't just jump in and start writing HTML, the same way you can't build a house by just pouring a foundation and putting up some walls. You need to know who will be using the site, and what they'll be using it for. You need some idea of what you'd like to draw their attention to during their visit. Overall, you need a strong, cohesive vision for the site that makes it both distinctive and usable. Information Architecture for the World Wide Web is about applying the principles of architecture and library science to web site design. Each web site is like a public building, available for tourists and regulars alike to breeze through at their leisure. The job of the architect is to set up the framework for the site to make it comfortable and inviting for people to visit, relax in, and perhaps even return to someday. Most books on web development concentrate either on the aesthetics or the mechanics of the site. This book is about the framework that holds the two together. With this book, you learn how to design web sites and intranets that support growth, management, and ease of use. Special attention is given to: • • • The process behind architecting a large, complex site Web site hierarchy design and organization Techniques for making your site easier to search Information Architecture for the World Wide Web is for webmasters, designers, and anyone else involved in building a web site. It's for novice web designers who, from the start, want to avoid the traps that result in poorly designed sites. It's for experienced web designers who have already created sites but realize that something "is missing" from their sites and want to improve them. It's for programmers and administrators who are comfortable with HTML, CGI, and Java but want to understand how to organize their web pages into a cohesive site. The authors are two of the principals of Argus Associates, a web consulting firm. At Argus, they have created information architectures for web sites and intranets of some of the largest companies in the United States, including Chrysler Corporation, Barron's, and Dow Chemical. Information Architecture for the World Wide Web Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com Preface Although information architecture may seem to be a high-handed and daunting term, it's really nothing new or mysterious. Think about it: why did the Ten Commandments come to us as two huge stone tablets? Perhaps Moses preferred a trifold design, or a portable wallet-size version, only to be overruled by his Project Manager. In any case, someone decided how to present the information to that audience of potential users milling about at the foot of Mount Sinai. From clay-tablet scribes to medieval monks to the folks who organize your daily newspaper, information architects have contributed in subtle but important ways to our world. Information architects have balanced the whims of authority with those of unforgiving users of every stripe, while forcibly fitting their efforts into the constraints of the available information technologies. In many cases, information architects have been responsible for major advancements in those technologies. The World Wide Web is the latest advancement in information technology, and, as with the previous innovations, certain principles carry over and others must be completely reexamined and overhauled. Because the Web integrates so many technologies and content types into a single interface, it challenges designers of web sites and intranets greatly. page 1 Information Architecture for the World Wide Web Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com Our Perspective We believe that truly successful web sites, especially large and complex ones, demand the expertise of professionals from many different disciplines. Besides information architects, great sites also require the skills of programmers, graphic designers, technical specialists, marketers, copywriters, project managers, and others. This book concentrates on the skills needed for information architecture; although we discuss these other disciplines when we can, we are not graphic designers, programmers, or anything but information architects, so everything we say about those areas should be taken with a very large grain of salt. As information architects, two major factors influence us: • Our professional backgrounds in the field of information and library studies. • Our experience in creating information architectures for large, complex web sites, primarily for corporate clients. Many librarians have responded slowly to new information technologies like the Web. Some librarians feel that their value as professionals will be diminished as "virtual libraries" supplant those filled with physical books and periodicals. Many librarians fear that the public will bypass them and go directly to the source via the Internet. The truth is, however, that skills in information organization and access are more and more necessary in this era of information explosion. We have found that the demand for our skills in classifying and organizing information in web sites has grown beyond our wildest dreams, so we believe that you, your sites, and their users will benefit from our profession's perspective. Between us, we have many years of experience in creating information architectures for web sites and intranets. At Argus Associates, our consulting firm, we concentrate on this area almost exclusively, and we have helped lots of large clients develop architectures that provide firm foundations for high quality web sites. We also have the benefit of working with and learning from experts from other companies who have backgrounds in other disciplines (our joint venture is called, aptly, Allied Studios). Besides our positive experiences, being in the "business" has given us many opportunities to make mistakes and ample time to learn from them. We hope you will benefit by learning from our mistakes as well as our successes. You don't need a library degree to be a successful information architect. Despite the requirements listed in some job descriptions, it's hard to have had years of experience within this fledgling medium. More important than either of these two factors is common sense, plain and simple. The Web is too new for anyone to feel secure in claiming that there is a "right way" to do things. Web sites are multifaceted, and can support many different ways of presenting information. This book clarifies different approaches to web site architecture, and provides you with the tools and concepts you need to determine the best approach for your site. page 2 Information Architecture for the World Wide Web Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com Who This Book Is For We're convinced that everyone, novice and wizard, should invest considerable time and energy into their web site's information architecture, especially if the goal is to build a large, complex web site or intranet. As we don't use lots of technical jargon, and because the topic of information architecture is so centered around users, we wrote this book to be accessible to anyone who has used the World Wide Web more than once or twice. The reality is that most novice site developers are blinded by the excitement created by the Web's technical and graphical possibilities and don't immediately key in on the intangible value of information architecture. So this book probably will be most beneficial to readers who already have a site under their belt, particularly: • Anyone who maintains a web site, intranet, or extranet where users get lost. • Anyone who maintains a web site, intranet, or extranet where users have difficulty finding the information they need. • Anyone who faces huge amounts of complex content and wonders how they'll ever organize the terrible mess into a usable and useful web site or intranet. • Anyone who confuses web page design with web site design. The authors work exclusively as information architecture consultants for large corporate clients; knowing our background will help you understand our biases. However, this book isn't written solely for people who work as outside consultants to corporations. For example, when we talk about clients, don't let that stop you from reading on; chances are that, without knowing it, you also have clients. It might be your boss or other coworkers. It might be the other members of your web development team. Maybe in a way you're the client. The guidelines for working with a client will hold true regardless of whether the client is from your organization, another organization, or yourself. page 3 Information Architecture for the World Wide Web Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com How To Use This Book This is not the typical O'Reilly animal book that tells you how to build a Unix firewall machine from a box of toothpicks and an old coffee maker. There are no code listings, no listings of function parameters, and no workarounds on little-known bugs in SunOS 4.1.4. While the content may be different, the format of this book is much the same: first we tell you why you need to know something, then we tell you what you need to know, and then we show you how to put it to practical use. Here is a description of the contents: Chapter 1 forces you to walk in the shoes of site users, ensuring that you'll consider their needs as you design the architecture. Chapter 2 provides you with some context for the field, and describes the information architect's role in developing web sites. Chapter 3 describes options for building organization structures, the backbones of any site, and organization schemes that meet the needs of your site's various audiences. Chapter 4 helps you to choose from among the various ways that you can make your site browsable. Chapter 5 provides you with approaches to determining and creating effective and descriptive content labels that your site's users will understand. Chapter 6 helps you to understand how people really search, and describes indexing and search interface improvements that result in better searching performance. Chapter 7 makes sure you're prepared to move forward by helping you to learn about the site's mission and vision, budget, timeline, audiences, content, and functionality. Chapter 8 provides you with the tools and approaches you need to capture the ideas that will drive the information architecture. Chapter 9 describes how you and your blueprints will affect and guide the production of the site. Chapter 10 is a case study that demonstrates the evolution of an information architecture for a real client. While this book stands on its own, we also encourage you to learn more about the disciplines from which information architecture borrows many of its principles. In Chapter 11 - Selected Bibliography, we've listed several publications that might be interesting to you as further reading. page 4 Information Architecture for the World Wide Web Simpo PDF Merge and Split Unregistered Version - http://www.simpopdf.com Text Conventions In this book, we follow these conventions: • Italics are used for email addresses, URLs, and for emphasis. • Courier is used for code examples. Other (Really Important) Conventions In this book, we talk about web sites. Not web pages, not home pages. Web sites. Why are we so hung up on this term? Because a great wrong has been committed, and it's time to right it. You see, somewhere, sometime way back in early Web pre-history when the terminology of the Web first got started, someone decided that home pages were cool. So, the people who were creating content for the Web began thinking of their output as pages. Discrete, singular. Stand-alone. Sure, these pages were linked to other pages, but the emphasis was placed on the page as the ultimate product. The Web is magical. It allows us to link together so many things in ways never before possible. It is fantastic that an image of Shakespeare can link to a page that provides a short biography of the great Bard, which can, in turn, link to another page that opens us up to the fascinating history of Elizabethan England. And so on. The whole of those pages and their links is much greater than the sum of the parts. That whole is what we call a web site. Thinking in terms of web pages or home pages too easily limits your field of vision to the trees and not the forest. The goal of this book is to help you master web architecture so that you can design wonderful forests. So from here on, think in terms of sites first and foremost. We also should clarify that we use the term web site to include sites available via the Internet, intranets, and extranets. We hope you'll find this book useful regardless of what type of web site you are developing. page 5
