    Abstract
    Relevance Ranking in Online-Katalogen ist zwar kein neues Thema, doch liegt dazu nicht allzu viel Literatur vor, die das Prädikat "ernstzunehmen" verdient. Dies ist zum einen darin begründet, dass das Interesse an der Ausgabe ranggereihter Ergebnislisten auf Seiten aller Beteiligter (Bibliothekare, Softwarehersteller, Benutzer) traditionell gering war. Zum anderen ging die seit einigen Jahren populär gewordene Kritik an den bestehenden OPACs vielfach von einer unzureichenden Wissensbasis aus und produzierte oft nur polemische oder emotional gefärbte Beiträge, die zum Thema Ranking wenig beitrugen. ... Der hier beschriebene Test ist natürlich in keiner Weise erschöpfend oder repräsentativ. Dennoch gibt er, wie ich glaube, Anlass zu einiger Hoffnung. Er lässt vermuten, dass die "neuen" OPACs - zumindest was das Relevance Ranking betrifft - auf dem Weg in die richtige Richtung sind. Wie gut es wirklich gelingen wird, die Rankingleistung von Suchmaschinen wie Google, die unter völlig anderen Voraussetzungen arbeiten, einzuholen, wird aber erst die Zukunft zeigen.

    Abstract
    Die Arbeitsgruppe PrimoImplementierung des Österreichischen Bibliothekenverbundes evaluierte im Winter 2010/11 Primo Central, den Discovery und Delivery Service von Ex Libris, im Zuge eines dreimonatigen Testzuganges und mehrerer Frage-und-Antwort-Runden mit Produktentwicklern von Ex Libris. Primo Central integriert hunderte Millionen anbieterseitig gelieferter Metadaten zu vornehmlich unselbständiger Literatur mit lokalen Beständen. In Bezug auf viele Forschungsgebiete wurde Primo Central als inhaltsreich empfunden, hauptsächlich hinsichtlich wissenschaftlicher Zeitschriftenaufsätze. Es deckte die Bestände einer großen und einer mittleren Universaluniversitätsbibliothek gut ab. Das Fehlen nationaler (deutschsprachiger) und regionaler Titel schränkt die Anwendbarkeit für Suchen nach österreichischem und deutschem Recht wesentlich, für Suchen in den Bereichen Wirtschaft, Psychologie und Bauingenieurwesen teilweise ein. Primo Central wird regelmäßig aktualisiert, ist jedoch notwendigerweise weniger aktuell als Verlagsplattformen oder PubMed, demzufolge auch weniger aktuell als Federated Search-Systeme wie MetaLib. Die dauerhafte Verfügbarkeit von Datenquellen in Primo Central kann von Ex Libris nicht garantiert werden. Die Metadaten der in Primo Central indexierten Ressourcen kommen derzeit nur zu einem geringen Teil vom Verlag selbst (der Großteil über CrossRef und IngentaConnect ), und enthalten daher oft keine inhaltliche Erschließung. Die Suchmöglichkeiten und die Reihung der Treffer nach Relevanz sind vergleichbar mit Google Scholar. Zusätzliche Funktionalitäten von Primo Central betreffen die Möglichkeit der Facettierung der Suchergebnisse und die Einschränkung der Treffer auf an der jeweiligen Bibliothek verfügbare Volltexte. Die Implementierung von Primo Central verlief schnell und problemlos. Voraussetzungen für den Einsatz von Primo Central sind die Verwendung von Promo als Bibliothekssuchmaschine oder von MetaLib als Federated Search System und der Einsatz eines Link Resolvers (nicht zwingend SFX).
