    Abstract
    Investigates how linkage environments in a hypertext based bibliographic retrieval system affect retrieval performance for novice and experienced searchers, 2 systems, 1 with inter record linkages to authors and descriptors and 1 that also included title and abstract keywords, were tested. No significant differences in retrieval performance and system usage were found for most search tests. The enhanced system did provide better performance where title and abstract keywords provided the most direct access to relevant records. The findings have implications for the design of bilbiographic information retrieval systems using hypertext linkages

    Abstract
    Folgender Beitrag beschäftigt sich mit der Konzeption und Durchführung von nachhaltigen Evaluationen von Information Retrieval Systemen mit Visualisierungskomponenten. Bisherige Evaluationsansätze differieren sowohl in der Methodenauswahl als auch Untersuchungsanlage, wie eine State-of-the-Art-Analyse aufzeigt. Im Anschluss werden die größten Herausforderungen, die sich bei Evaluationen dieser Art ergeben mit Vorschlägen zu potenziellen Lösungsansätzen diskutiert. Auf der Grundlage eines morphologischen Rahmens wird ein Bezugsrahmen für die Evaluation von Information Retrieval Systemen mit Visualisierungskomponenten vorgeschlagen, das einen integrierten Ansatz zur Kombination geeigneter Methoden aus dem Bereich der Usability-Evaluation und der Retrievaleffektivitäts-Evaluation verfolgt.

    Abstract
    Examines 3 aspects of keyword searching to see if defaulting to keyword searches might serve as a solution to the problems users find when performing subject searches in OPACs. Investigates if keyword searching produces useful results; if people who use keyword searches to find information on a subject report that they are satisfied with the results; and how keyword searching and controlled vocabulary searching are offered and explained in currently available OPAC interfaces. Concludes that both keyword and controlled vocabulary searching ought to be easily available in an OPAC, and that improvements need to be made in explanation and help offered to subject searchers
