Abstract

Gedruckte Medien, wie Bücher, Zeitschriften und Zeitungen sind kulturhistorisch und marktwirtschaftlich wichtige Informationsquellen auf dem Weg zur Wissensgesellschaft. Um sie elektronisch verfügbar zu machen, um sie bereitzustellen und zu vermarkten, werden vorhandene Dokumente digitalisiert, mit besonderen Analyseverfahren inhaltlich erschlossen und über Web-Portale zur Verfügung gestellt. Es ist jedoch eine besondere Herausforderung, sicher und schnell auf zentral verwaltete Dokumentbestände über das Internet zuzugreifen. Beim Abruf von qualitativ hochwertigen Digitalisaten werden große Datenmengen übertragen. Dadurch steigt der Bandbreitenbedarf und die Zugriffszeiten verlängern sich. Außerdem unterliegen urheberrechtlich geschützte Dokumente besonderen gesetzlichen Beschränkungen. Für die wirtschaftliche Verwertung von digitalisierten Druckmedien ist daher neben der inhaltlichen Erschließung auch der Einsatz von geeigneten Leseanwendungen notwendig. Das Fraunhofer-Institut Intelligente Analyse- und Informationssysteme (IAIS) entwickelt Techniken,um diese Herausforderungen zu meistern.

Abstract

We investigate the extent to which open-access (OA) journals and articles in biology, computer science, economics, history, medicine, and psychology are indexed in each of 11 bibliographic databases. We also look for variations in index coverage by journal subject, journal size, publisher type, publisher size, date of first OA issue, region of publication, language of publication, publication fee, and citation impact factor. Two databases, Biological Abstracts and PubMed, provide very good coverage of the OA journal literature, indexing 60 to 63% of all OA articles in their disciplines. Five databases provide moderately good coverage (22-41%), and four provide relatively poor coverage (0-12%). OA articles in biology journals, English-only journals, high-impact journals, and journals that charge publication fees of $1,000 or more are especially likely to be indexed. Conversely, articles from OA publishers in Africa, Asia, or Central/South America are especially unlikely to be indexed. Four of the 11 databases index commercially published articles at a substantially higher rate than articles published by universities, scholarly societies, nonprofit publishers, or governments. Finally, three databases-EBSCO Academic Search Complete, ProQuest Research Library, and Wilson OmniFile-provide less comprehensive coverage of OA articles than of articles in comparable subscription journals.

Abstract

You were going to get one-click access to the full text of nearly every book that's ever been published. Books still in print you'd have to pay for, but everything else-a collection slated to grow larger than the holdings at the Library of Congress, Harvard, the University of Michigan, at any of the great national libraries of Europe-would have been available for free at terminals that were going to be placed in every local library that wanted one. At the terminal you were going to be able to search tens of millions of books and read every page of any book you found. You'd be able to highlight passages and make annotations and share them; for the first time, you'd be able to pinpoint an idea somewhere inside the vastness of the printed record, and send somebody straight to it with a link. Books would become as instantly available, searchable, copy-pasteable-as alive in the digital world-as web pages. It was to be the realization of a long-held dream. "The universal library has been talked about for millennia," Richard Ovenden, the head of Oxford's Bodleian Libraries, has said. "It was possible to think in the Renaissance that you might be able to amass the whole of published knowledge in a single room or a single institution." In the spring of 2011, it seemed we'd amassed it in a terminal small enough to fit on a desk. "This is a watershed event and can serve as a catalyst for the reinvention of education, research, and intellectual life," one eager observer wrote at the time. On March 22 of that year, however, the legal agreement that would have unlocked a century's worth of books and peppered the country with access terminals to a universal library was rejected under Rule 23(e)(2) of the Federal Rules of Civil Procedure by the U.S. District Court for the Southern District of New York. When the library at Alexandria burned it was said to be an "international catastrophe." When the most significant humanities project of our time was dismantled in court, the scholars, archivists, and librarians who'd had a hand in its undoing breathed a sigh of relief, for they believed, at the time, that they had narrowly averted disaster.
