Social and interactional practices for disseminating current awareness information in an organisational setting.
Current awareness services are designed to keep users informed about recent developments based around user need profiles. In organisational settings, they may operate through both electronic and social interactions aimed at delivering information that is relevant, pertinent and current. Understanding these interactions can reveal the tensions in current awareness dissemination and help inform ways of making services more effective and efficient. We report an in-depth, observational study of electronic current awareness use within a large London law firm. The study found that selection, re-aggregation and forwarding of information by multiple actors gives rise to a complex sociotechnical distribution network. Knowledge management staff act as a layer of āintelligent filtersā sensitive to complex, local information needs; their distribution decisions address multiple situational relevance factors in a situation fraught with information overload and restrictive time-pressures. Their decisions aim to optimise conflicting constraints of recall, precision and information quantity. Critical to this is the use of dynamic profile updates which propagate back through the network through formal and informal social interactions. This supports changes to situational relevance judgements and so allows the network to āself-tuneā. These findings lead to design requirements, including that systems should support rapid assessment of information items against an individualās interests; that it should be possible to organise information for different subsequent uses; and that there should be back-propagation from information consumers to providers, to tune the understanding of their information needs

Grundlagen der Informationswissenschaft
Die 7. Ausgabe der "Grundlagen der praktischen Information und Dokumentation" (Erstausgabe 1972) heiĆt jetzt: āGrundlagen der Informationswissenschaft". Der Bezug zur Praxis und zur Ausbildung bleibt erhalten, aber der neue Titel trƤgt dem Rechnung, dass die wissenschaftliche theoretische Absicherung fĆ¼r alle Bereiche von Wissen und Information, nicht nur in der Fachinformation, sondern auch in den Informationsdiensten des Internet immer wichtiger wird. FĆ¼r die Grundlagen sind 73 Artikel in 6 Hauptkapiteln vorgesehen. Viele Themen werden zum ersten Mal behandelt, z.B. Information und Emotion, Informationelle Selbstbestimmung, Informationspathologien. Alle BeitrƤge sind neu verfasst
