Abstract
Zur Erreichung einer für den Besucher optimal ausgerichteten Website sind wesentliche Aufgaben bereits in der Vorbereitungsphase zu erarbeiten, unter anderem Zielgruppenermittlung, Bedürfnisfeststellung sowie Strukturierung des Angebots. Eine gute oder auch weniger gelungene Umsetzung dieser Kriterien kann an Beispielen aus der Praxis am Besten veranschaulicht werden. Um eine ungefähre Vergleichbarkeit der Angebote zu erhalten, sind im Folgenden nur die Seiten von Öffentlichen Bibliotheken gleicher Größenklasse nach Bix verwendet worden, und zwar der Klasse 4 (15 000 bis 30 000 Einwohner). Hier ist die Notwendigkeit einer allgemeinen Verbesserung des virtuellen Angebots am meisten gegeben.

Mit einer Übersicht zu Usability-Kriterien: Ten Usability Heuristics I. Visibility ofsystem status The system should always keep users informed about what is going on, through appropriate feedback within reasonable time. II. Match between system and the real world The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order. III. User control and freedom Users often choose system functions by mistake and will need a clearly marked »emergency extra to leave the unwanted state without having to go through an extended dialogue. Support undo and redo. IV. Consistency and standards Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions. V. Error prevention Even better than good error messages is a careful design which prevents a problem from occurring in the first place. VI. Recognition rather than recall Make objects, actions, and options visible. The user should not have to remember information from one Part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate. VII. Flexibility and efficiency of use Accelerators - unseen by the novice user- may often speed up the interaction for the expert user such that the system can cater to both inexperienced and experienced users. Allow users to tailor frequent actions. VIII. Aesthetic and minimalist design Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility. IX. Help users recognize, diagnose, and recover from errors Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution. X. Help and documentation Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused an the user's task, list concrete steps to be carried out, and not be too large.
