The third section is opened by an emblematic article of Barbara Tillett about the impact the implementation of the FRBR model has on future library catalogues. The novelty brought by the model is expected to influence both the cataloguing codes and practice and the design of the new library systems. Implementation issues are also treated by Maja flumer and Gerhard Riesthuis in an article describing the application of the FRBR model to the Slovenian national bibliography. Maja flumer reports another instance of the implementation of FRBR, namely the European Research Initiative. The author describes the initiative originating from FLAG (European Library Automation Group) and IFLA and proposes the agenda of future research and action. The next experiment described by Thomas Hickey and Edward O'Neil brings to our attention an algorithm developed at OCLC that identifies sets of works for collocation purposes. By so doing, the FRBR model is applied to the aggregate works existing in the huge and rapidly growing OCLC's WorldCat. An application of the FRBR conceptual approach to UNESCO's ISIS retrieval software is presented by Roberto Sturman as his personal experiment. The database structure and the relationships between entities are explained together with their functionalities in three different interfaces. The practical benefits of applying the FRBR model to enhanced displays of bibliographic records in online catalogues are explored in the article of Jacqueline Radebaugh and Corey Keith. The FRBR Display Tool, based on XML technologies, was "developed to transform bibliographic data found in MARC 21 record files into meaningful displays by grouping them into [...] FRBR entities" (p. 271). The last section, by Dick Miller, is dedicated to a rather futuristic view of cataloguing, which the editor calls "a revolutionary alternative to the comparatively conservative and `traditional' approach that FRBR represents" (p. 11). XOBIS, like the previously mentioned application, uses XML technologies to reorganize bibliographic and authority data elements into an integrated structure.

Die Murmel liefert das Hauptthema des Buchs. Die Seele, das Ich, ist eine Illusion. Es ist eine »seltsame Schleife« (a strange loop), die ihrerseits von einer Unzahl von Schleifen auf einem niedrigeren Niveau erzeugt wird. So kommt es, dass der Klumpen Materie innerhalb unseres Schädels nicht nur sich selbst beobachtet, sondern sich dessen auch bewusst ist. Seltsame, genauer: selbstbezügliche Schleifen faszinieren Hofstadter seit jeher. Er sieht sie überall. Sie sind das Herzstück von Gödels berühmtem Unbeweisbarkeitssatz. Sie lauern in den »Principia Mathematica« von Russell und Whitehead, stets bereit, die Fundamente der Mathematik zu untergraben. Ihre kürzeste Form sind logische Paradoxa wie »Dieser Satz ist falsch« oder die Karte, auf deren einer Seite steht »Der Satz auf der Rückseite ist wahr« und auf der anderen »Der Satz auf der Rückseite ist falsch«. In Kapitel 21 führt er ein verstörendes Gedankenexperiment ein, das auch Thema zahlreicher Sciencefiction-Geschichten ist: Ein Mann wird, wie in »Raumschiff Enterprise«, auf einen fremden Planeten und zurück gebeamt, indem eine Maschine ihn Molekül für Molekül abscannt und die Information an den Zielort übermittelt, wo sie zur Herstellung einer exakten Kopie dieses Menschen dient. Wenn dabei das Original zerstört wird, entsteht kein philosophisches Problem. Wenn es aber erhalten bleibt - oder mit derselben Information zwei Kopien hergestellt werden -, entsteht ein Paar identischer Zwillinge mit identischen Erinnerungen. Ist der so gebeamte Mensch derselbe wie das Original oder ein anderer?
