PaperChase is a computerized bibliographic retrieval system that permits users without previous training to search the medical literature themselves at any time of the day or night. The database for PaperChase consists of approximately 425,000 references from 258 journals dating back eight years—nearly all the references shelved in the library of our hospital. In its first year of deployment, 1,032 users conducted 8,459 searches, during which they displayed 399,821 references and selected 97,869 of them for printing. The most common reason for using PaperChase is to answer a question of medical importance. As the results of the search are displayed, the titles of the retrieved references flash by; often one or more of them contain a declarative medical statement that answers the question of interest. To facilitate rapid review of these medical statements, we provided a new means to display references—just the titles, but four at a time. Examples are given which illustrate how users of PaperChase can find what they are looking for without consulting bound volumes.

PaperChase ist ein computererstelltes bibliographisches Retrieval-System, das es dem Benutzer ermöglicht, zu jeder Tages- und Nachtzeit ohne vorherige Ausbildung selbst Suchen nach medizinischer Literatur durchzuführen. Die Datenbank von PaperChase besteht aus rund 425000 Literaturhinweisen aus 258 Zeitschriften der letzten acht Jahre, wobei fast die gesamte zitierte Literatur in unserer Krankenhausbibliothek verfügbar ist. Im ersten Verwendungsjahr führten 1 032 Benutzer 8459 Suchen durch, in deren Verlauf sie 399821 Literaturhinweise ermittelten und 97869 davon ausdrucken ließen.

Der häufigste Grund für die Benutzung von PaperChase ist die Beantwortung einer Frage von Bedeutung in der Medizin. Sobald die Ergebnisse der Suche ausgegeben werden, leuchten die Titel der aufgefundenen Literaturhinweise auf; häufig enthält eine oder mehrere von ihnen eine deklarative medizinische Aussage, die die betreffende Frage beantwortet. Um eine rasche Übersicht über diese medizinischen Aussagen zu ermöglichen, boten wir eine neue Form der Ausgabe von Literaturhinweisen an — nur die Titel, aber vier auf einmal. Beispiele werden gegeben, die erhellen, wie die Benutzer von PaperChase das finden können, wonach sie suchen, ohne gebundene Bücher zu konsultieren.
