Drop-down menus are often more trouble than they are worth and can be confusing because Web designers use them for several different purposes. Also, scrolling menus reduce usability when they prevent users from seeing all their options in a single glance.

Web users go straight for content and ignore navigation areas. Limited structural navigation and local navigation still help, but general navigation should be avoided and generic links minimized to the truly useful.

Anything done by more than 90% of big
sites becomes a de-facto design standard that must be followed unless
an alternative design achieves 100% increased usability.

iCab, a web browser introduced in 1999, uses the LINK tags from the page headers to provide additional navigation links to the users. This structural navigation provides a valuable alternative to users.

People are not frogs, making it difficult to navigate 3D computer spaces: stick to 2D for most navigation designs. Shun virtual reality gimmicks that distract from users' goals

Instead of emulating the real world, websites should build on the strengths of the medium and go beyond what's possible in physical reality: be non-linear, customize service, ignore geography.

The 1997 redesign of the Sun Microsystems' Web site aimed to improve the visual appearance, ease of navigation, and performance of the Web site.

Some browsers pop up a short explanation of a link *before* the user selects it. Such link titles can give users a preview of where the link will lead, improve their navigation, and reduce disorientation.

Four years of progress in Web browsers have given us more fancy presentation but almost no improvements in helping users navigate the Web and getting the information they need.

There is now a profusion of choices when it comes to web browsers, and market shares can change rapidly. The only certain trend on the Internet and WWW is that change happens so quickly that it is impossible to predict what will happen. Even so, the following changes ought to happen, so hopefully they will be the next trends.

This chapter from Jakob Nielsen's 1995 book Multimedia and Hypertext: The Internet and Beyond explores a variety of mechanisms for helping users navigate in digital environments including history lists, bookmarks, overview diagrams, and navigational dimensions and metaphors.

Hypertext systems include a Presentation level, a Hypertext Abstract Machine (HAM) level, and a Database level. The following sections describe each of the levels in further detail, starting at the bottom. (Chapter 5 from Jakob Nielsen's book, Multimedia and Hypertext.)

This paper presents the methods used to design the user interface and overall structure of Sun Microsystems' first intranet. Sun had an extensive set of information available on the WWW with the home page as the access point, but also wanted to provide employees access to internal information that could not be made available to the Internet at large.

A review of the Macintosh CD-ROM versions of The Manhole, the Time Table of History, and the Electronic Whole Earth Catalog with emphasis on their usability and their support of hypertext navigation. Based on the discussion of these hypertexts the following general principles are found to be useful for analyzing hypertext user interfaces: Navigational dimensions and their explicitness, directionality and literalness, landmarks, locational orientation, history lists, and backtrack mechanisms.
