    Abstract
    Einleitung In der deutschen und internationalen Bibliothekslandschaft entstehen zahlreiche Informationsportale, die eigene Ziele verfolgen. Sie differieren in der Ausrichtung ihrer Angebote und Dienste, zeigen aber gelegentlich auch Oberschneidungen. Erstrebenswert ist es, solche Überschneidungen gering zu halten und die mit einem Alleinstellungsmerkmal versehenen Dienstleistungen auszubauen. Auf lokaler, regionaler und auch auf nationaler Ebene sind Arbeitsteilung und Kooperation angebracht, weil der Aufbau von Portalen teuer ist. Die unterschiedlichen Portale sollten so miteinander vernetzt werden, dass sich die Dienstleistungen sinnvoll ergänzen. Die KOBV-Zentrale möchte dieses Ziel erreichen und die Dienste des KOBV-Portals nutzbringend mit anderen Informationsportalen in Verbindung bringen. Dazu müssen zuvor die Dienstleistungen, die Zielgruppe, die Kriterien für die Ressourcenauswahl und die Abgrenzung zu anderen Portalen in einem Profil klar definiert werden. Stellt man mehrere dieser deklarierten Profilbeschreibungen nebeneinander, werden schließlich die Grenzen und Verknüpfungspunkte einzelner Portale sichtbar. Das KOBV-Portal ist eine Weiterentwicklung der bewähren KOBV-Suchmaschine, die als virtueller Verbundkatalog der Länder Berlin und Brandenburg aufgebaut worden ist. Im KOBV-Portal wird ein Bestandsnachweis aller lizenzieren Ressourcen in der Region sowie freier, wissenschaftlich relevanter Ressourcen angeboten, die insbesondere für die Angehörigen der Wissenschaftsinstitutionen und die Nutzer der Öffentlichen Bibliotheken in BerlinBrandenburg von Interesse sind. Zu diesem Zweck werden zukünftig mit lokalen, regionalen und nationalen Informationspokalen Metadaten zu Ressourcen ausgetauscht, um die Qualität des Informationswerts der einzelnen Portale auf Basis der Gegenseitigkeit zu erhöhen. Für ein solches Metadata-Sharing und eine gegenseitige Integration von Dienstleistungen werden Kooperationen mit anderen Anbietern von Portalen angestrebt. Dabei bilden die einzelnen Portale jeweils ihr eigenes unverwechselbares Profil aus. Befürchtungen, dass es nach einer Kooperation zu Unschärfen zwischen den einzelnen, wenn auch noch nicht explizit formulierten Portalprofilen kommen wird, soll mit dieser ersten Positionsbestimmung entgegengewirkt werden. Die KOBV-Zentrale versteht das als wichtige Maßnahme zur weiteren Vernetzung von Angeboten über Portale und möchte andere Portalanbieter dazu aufrufen, ihrerseits ein solches Profil aufzustellen.
